Prior to this change, all alert instance writes and deletes happened
individually, in their own database transaction. This change batches up
writes or deletes for a given rule's evaluation loop into a single
transaction before applying it.
These new transactions are off by default, guarded by the feature toggle "alertingBigTransactions"

storing and deleting 100 instances.

This change also updates some of our tests so that they run successfully against postgreSQL - we were using random Int64s, but postgres integers, which our tables use, max out at 2^31-1
* update RouteDeleteAlertRules rules to update as a group
* remove expecter from scheduler mock to support variadic function
* create function to check for provisioning status + tests
Co-authored-by: Alexander Weaver <weaver.alex.d@gmail.com>
* remove support for bus from scheduler
* rename event to FolderTitleUpdated and fire only if title has changed
* add method to increase version of all rules that belong to a folder
* update ngalert service to subscribe to folder title change event call data store and update scheduler
* add tests
* move fake FakeExternalAlertmanager to sender package
* move tests from scheduler to router
* update alerts router to have all fields private
* update scheduler tests to use sender mock
* add tests for cache getOrCreate
* update ProcessEvalResults to accept extra lables
* extract to getRuleExtraLabels
* move populating of constant rule labels to extra labels
Migrations:
* add a new column alert_group_idx to alert_rule table
* add a new column alert_group_idx to alert_rule_version table
* re-index existing rules during migration
API:
* set group index on update. Use the natural order of items in the array as group index
* sort rules in the group on GET
* update the version of all rules of all affected groups. This will make optimistic lock work in the case of multiple concurrent request touching the same groups.
UI:
* update UI to keep the order of alerts in a group
* create AlertGroupKey structure
* update PrometheusSrv.
- extract creation of RuleGroup to a separate method. Use group key for grouping
* update RuleSrv
- update calculateChanges to use groupKey
- authorize to use groupkey
* add custom diff reporter DiffReporter that reports only paths that have a difference
* create Diff method for AlertRule that returns DiffReport, which is an alias for []Diff
Tests:
* create copy method for AlertRule in testing
* create GenerateAlertQuery method in testing
* Update API controller
- add validation of rules API model
- add function to calculate changes between the submitted alerts and existing alerts
- update RoutePostNameRulesConfig to validate input models, calculate changes and apply in a transaction
* Update DBStore
- delete unused storage method. All the logic is moved upstream.
- upsert to not modify fields of new by values from the existing alert
- if rule has UID do not try to pull it from db. (it is done upstream)
* Add rule generator
