* chore: AzureMonitor typescript typings
Removes some types and using @grafana/ui types instead.
Adds some typing for the AzureMonitor query.
Also adds a getSubscriptions function that will used in the query
editor.
* fix: AzureMonitor adds back editor for annotation queries
This must have been broken for a month or more. Now possible to
edit annotation queries again.
* feat: Azure Monitor - support for multiple subscriptions
Adds a new dropdown for subscriptions in the query editor.
Defaults to the subscription id in jsonData for queries
that have no subscription id.
* feat: adds Azure Logs multi subscriptions support
The subscription id is needed for fetching the list of
workspaces. Adds support to the Log Analytics datasource
and to the annotations for Log Analytics to be able to
choose between multiple subscriptions.
* feat: AzureMonitor config page with multiple subs
Adds support for multiple subscriptions for the different
variations of configuring Azure Monitor and Azure Logs.
To be able to show a list of subscriptions, the config
has to be saved first - the plugin route fetches the
tenant id, client id and client secret from the database
so a call to get subscriptions requires that those
fields are saved first. If the page has not saved then
the use can manually paste in a subscription id.
* feat: support for multi subs in Azure Monitor variables
Adds an optional subscription parameter to the template
variable macros. Also adds a Subscriptions macro.
* fix: remove some implicit anys from tests
* wip: began work off removing meta and pluginExports from DataSourceApi interface
* WIP: changing how plugins are exports and loaded
* Down the refactoring rabit hole that keeps expanding
* TestData now returns DataSourcePlugin
* Refactoring: fixed app config page loading, type renamings and more typings
* Refactor: Correct casing on DatasourceStatus => DataSourceStatus
