add proprtype

after a few try, I think it can work this way :

 * everything is in one store: xoApi, session, even component states. try to use boolean when possible to simplify usage in components
 * components states should rarely be used : let components be stateless, a pure function of their props
 * use connect on high level component to give them access to part of the store and the actions. A component should not have access to the full store and action.
 * use event to get data back from child components ( if they can't dispatch action themselves)
 * redux-thunk allow to dispatch multiple action in cascade (even async one) , like want to save->saving ->saved (or errored)
 * use imutable object, this will allow faster performance in the long run

-# @xen-orchestra/cron [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
-
-> Focused, well maintained, cron parser/scheduler
-
-## Install
-
-Installation of the [npm package](https://npmjs.org/package/@xen-orchestra/cron):
-
-```
-> npm install --save @xen-orchestra/cron
-```
-
-### Pattern syntax
-
-```
-<minute> <hour> <day of month> <month> <day of week>
-```
-
-
-Each entry can be:
-
-- a single value
-- a range (`0-23` or `*/2`)
-- a list of values/ranges (`1,8-12`)
-
-A wildcard (`*`) can be used as a shortcut for the whole range
-(`first-last`).
-
-Step values can be used in conjunctions with ranges. For instance,
-`1-7/2` is the same as `1,3,5,7`.
-
-| Field            | Allowed values |
-|------------------|----------------|
-| minute           | 0-59           |
-| hour             | 0-23           |
-| day of the month | 1-31 or 3-letter names (`jan`, `feb`, …) |
-| month            | 0-11           |
-| day of week      | 0-7 (0 and 7 both mean Sunday) or 3-letter names (`mon`, `tue`, …) |
-
-> Note: the month range is 0-11 to be compatible with
-> [cron](https://github.com/kelektiv/node-cron), it does not appear to
-> be very standard though.
-
-### API
-
-`createSchedule(pattern: string, zone: string = 'utc'): Schedule`
-
-> Create a new schedule.
-
-- `pattern`: the pattern to use, see [the syntax](#pattern-syntax)
-- `zone`: the timezone to use, use `'local'` for the local timezone
-
-```js
-import { createSchedule } from '@xen-orchestra/cron'
-
-const schedule = createSchedule('0 0 * * sun', 'America/New_York')
-```
-
-`Schedule#createJob(fn: Function): Job`
-
-> Create a new job from this schedule.
-
-- `fn`: function to execute, if it returns a promise, it will be
-  awaited before scheduling the next run.
-
-```js
-const job = schedule.createJob(() => {
-  console.log(new Date())
-})
-```
-
-`Schedule#next(n: number): Array<Date>`
-
-> Returns the next dates matching this schedule.
-
-- `n`: number of dates to return
-
-```js
-schedule.next(2)
-// [ 2018-02-11T05:00:00.000Z, 2018-02-18T05:00:00.000Z ]
-```
-
-`Schedule#startJob(fn: Function): () => void`
-
-> Start a new job from this schedule and return a function to stop it.
-
-- `fn`: function to execute, if it returns a promise, it will be
-  awaited before scheduling the next run.
-
-```js
-const stopJob = schedule.startJob(() => {
-  console.log(new Date())
-})
-stopJob()
-```
-
-`Job#start(): void`
-
-> Start this job.
-
-```js
-job.start()
-```
-
-`Job#stop(): void`
-
-> Stop this job.
-
-```js
-job.stop()
-```
-
-## Development
-
-```
-# Install dependencies
-> yarn
-
-# Run the tests
-> yarn test
-
-# Continuously compile
-> yarn dev
-
-# Continuously run the tests
-> yarn dev-test
-
-# Build for production (automatically called by npm install)
-> yarn build
-```

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at julien.fontanet@vates.fr. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

-# xen-api [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
-
-> Connector to the Xen API
-
-Tested with:
-
-- XenServer 7.3
-- XenServer 7.2
-- XenServer 7.1
-- XenServer 7
-- XenServer 6.5
-- XenServer 6.2
-- XenServer 5.6
-
-## Install
-
-Installation of the [npm package](https://npmjs.org/package/xen-api):
-
-```
-> npm install --save xen-api
-```
-
-## Usage
-
-### Library
-
-```javascript
-const { createClient } = require('xen-api')
-
-const xapi = createClient({
-  url: 'https://xen1.company.net',
-  allowUnauthorized: false,
-  auth: {
-    user: 'root',
-    password: 'important secret password'
-  },
-  readOnly: false
-})
-```
-
-Options:
-
-- `url`: address of a host in the pool we are trying to connect to
-- `allowUnauthorized`: whether to accept self-signed certificates
-- `auth`: credentials used to sign in (can also be specified in the URL)
-- `readOnly = false`: if true, no methods with side-effects can be called
-
-```js
-// Force connection.
-xapi.connect().catch(error => {
-  console.error(error)
-})
-
-// Watch objects.
-xapi.objects.on('add', objects => {
-  console.log('new objects:', objects)
-})
-```
-
-> Note: all objects are frozen and cannot be altered!
-
-Custom fields on objects (hidden − ie. non enumerable):
-- `$type`: the type of the object (`VM`, `task`, …);
-- `$ref`: the (opaque) reference of the object;
-- `$id`: the identifier of this object (its UUID if any, otherwise its reference);
-- `$pool`: the pool object this object belongs to.
-
-Furthermore, any field containing a reference (or references if an
-array) can be resolved by prepending the field name with a `$`:
-
-```javascript
-console.log(xapi.pool.$master.$resident_VMs[0].name_label)
-// vm1
-```
-
-### CLI
-
-A CLI is provided to help exploration and discovery of the XAPI.
-
-```
-> xen-api https://xen1.company.net root
-Password: ******
-root@xen1.company.net> xapi.status
-'connected'
-root@xen1.company.net> xapi.pool.master
-'OpaqueRef:ec7c5147-8aee-990f-c70b-0de916a8e993'
-root@xen1.company.net> xapi.pool.$master.name_label
-'xen1'
-```
-
-To ease searches, `find()` and `findAll()` functions are available:
-
-```
-root@xen1.company.net> findAll({ $type: 'vm' }).length
-183
-```
-
-## Development
-
-```
-# Install dependencies
-> npm install
-
-# Run the tests
-> npm test
-
-# Continuously compile
-> npm run dev
-
-# Continuously run the tests
-> npm run dev-test
-
-# Build for production (automatically called by npm install)
-> npm run build
-```
-
