This should only land once we are on Gerrit 3.x and happy with it. But
at this point the mysql reviewdb will not be used anymore and config for
it can be removed. We keep general mysql things like tools and backups
in place as the accountPatchReviewDb continues to live in MySQL.
This also comments out calls to jeepyb's welcome-message,
update-blueprint and update-bug entrypoints from the patchset-created
event hook, since they rely on database connections for the moment.
Calls to update-bug in change-abandoned and change-merged event
hooks are retained as those code paths don't rely on database
interaction nor attempt to load the removed configuration.

Files are bind-mounted into the container in different locations.
Set envvars pointing to the right places.
Also - we need to bind-mount the projects.yaml and projects.ini
files into the container.
While we're at it, move patchset-created to be a regular file.
