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.
* Use suggested value for uid
* update the snapshot
* use __expr__
* replace all -100 with __expr__
* update snapshot
* more changes
* revert redundant change
* Use expr.DatasourceUID where it's possible
* generate files
* 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
