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.
* Alerting: Don't stop the migration when alert rule tags are invalid
As we migrate we expect the `alertRuleTags` on a dashboard alert to be a JSON object. However, it seems this is not really validated by Grafana and an user can change the format to something else that the JSON parser is not able to marshal into a `map[string]string`.
Let's do a bit better by "attempting" to parse the tags and if we can't we'll simple return an empty map. The data is still there so if the user wishes they can go back, fix the data and attemp the migration again.
* Fix dashboard alert and nootifier migration for MySQL
* Fix POSTing Alertmanager configuration if no current configuration exists
in case the default configuration has not be stored yet
or has failed to get stored
* Change CreatedAt field type
* Not complete, put migration behind env flag for now:
UALERT_MIG=iDidBackup
* Important to backup, and not expect the same DB to keep working until the env trigger is removed.
* Alerting: Migrate dashboard alert permissions
* Do not use imported models
* Change folder titles
