Before db_metrics were all or nothing. Now `InTx` metrics are always recorded, and query metrics are opt in.
Adds instrumentation & logging around serialization failures in the database.
Joins in fields like `username`, `avatar_url`, `organization_name`,
`template_name` to `workspaces` via a **view**.
The view must be maintained moving forward, but this prevents needing to
add RBAC permissions to fetch related workspace fields.
* chore: remove InsertWorkspaceAgentStat query
InsertWorkspaceAgentStats (batch) exists. We only used the singular in
a single unit test place. Removing the single for the batch, reducing
the interface size.
Add `dbrollup` service that runs the `UpsertTemplateUsageStats` query
every 5 minutes, on the minute. This allows us to have fairly real-time
insights data when viewing "today".
