* Alerting: During legacy migration reduce the number of created silences
During legacy migration every migrated rule was given a label rule_uid=<uid>.
This was used to silence DatasourceError/DatasourceNoData alerts for
migrated rules that had either ExecutionErrorState/NoDataState set to
keep_state, respectively.
This could potentially create a large amount of silences and a high cardinality
label. Both of these scenarios have poor outcomes for CPU load and latency in
unified alerting.
Instead, this change creates one label per ExecutionErrorState/NoDataState when
they are set to keep_state as well as two silence rules, if rules with said
labels were created during migration. These silence rules are:
- __legacy_silence_error_keep_state__ = true
- __legacy_silence_nodata_keep_state__ = true
This will drastically reduce the number of created silence rules in most cases
as well as not create the potentially high cardinality label `rule_uid`.
This PR has two steps that together create a functional dry-run capability for the migration.
By enabling the feature flag alertingPreviewUpgrade when on legacy alerting it will:
a. Allow all Grafana Alerting background services except for the scheduler to start (multiorg alertmanager, state manager, routes, …).
b. Allow the UI to show Grafana Alerting pages alongside legacy ones (with appropriate in-app warnings that UA is not actually running).
c. Show a new “Alerting Upgrade” page and register associated /api/v1/upgrade endpoints that will allow the user to upgrade their organization live without restart and present a summary of the upgrade in a table.
* Alerting: Add clean_upgrade config and deprecate force_migration
Upgrading to UA and rolling back will no longer delete any data by default.
Instead, each set of tables will remain unchanged when switching between
legacy and UA. As such, the force_migration config has been deprecated
and no extra configuration is required to roll back to legacy anymore.
If clean_upgrade is set to true when upgrading from legacy alerting to Unified
Alerting, grafana will first delete all existing Unified Alerting resources,
thus re-upgrading all organizations from scratch. If false or unset,
organizations that have previously upgraded will not lose their existing Unified
Alerting data when switching between legacy and Unified Alerting.
Similar to force_migration, it should be kept false when not needed as it may
cause unintended data-loss if left enabled.

* Alerting: Keep track of individual org migration status
Save migration status per migrated org.
Change the meaning (and key/value) of the org_id=0 entry
to store the current (previous) config value used by alerting.
This is so we can know when to upgrade/downgrade by
comparing with the new config value in
UnifiedAlerting.IsEnabled.
This PR replaces the vendored models in the migration with their equivalent ngalert models. It also replaces the raw SQL selects and inserts with service calls.
It also fills in some gaps in the testing suite around:
- Migration of alert rules: verifying that the actual data model (queries, conditions) are correct 9a7cfa9
- Secure settings migration: verifying that secure fields remain encrypted for all available notifiers and certain fields migrate from plain text to encrypted secure settings correctly e7d3993
Replacing the checks for custom dashboard ACLs will be replaced in a separate targeted PR as it will be complex enough alone.
