This PR sets a constraint of 1MB on the provisioner job logs written to
the database. This is consistent with the constraint we place on
workspace agent logs:

It also adds a message printed to the front end about the provisioner
log overflow, and updates the message printed to the front end when
workspace startup logs exceed the max, as it was causing some customers
to think their startup script had failed to run.
* chore: rename startup logs to agent logs
This also adds a `source` property to every agent log. It
should allow us to group logs and display them nicer in
the UI as they stream in.
