* chore: convert workspace agent stats from json to table
* chore: convert agent stats to use a table
Backwards compatibility becomes hard when all agent stats are in a JSON blob.
We also want to query this table for new agents that are failing health checks
so we can display it in the UI.
* Fix migration using default values
- rbac: export rbac.Permissions
- dbauthz: move GetDeploymentDAUs, GetTemplateDAUs,
GetTemplateAverageBuildTime from querier.go to system.go
and removes auth checks
- dbauthz: remove AsSystem(), add individual roles for
autostart, provisionerd, add restricted system role for
everything else
feat: Add initial AuthzQuerier implementation
- Adds package database/dbauthz that adds a database.Store implementation where each method goes through AuthZ checks
- Implements all database.Store methods on AuthzQuerier
- Updates and fixes unit tests where required
- Updates coderd initialization to use AuthzQuerier if codersdk.ExperimentAuthzQuerier is enabled
