This adds a context to the session.RepositoryFactory, allowing
errors.NewDeprecated to be replaced with errors.New. It also removes the
common.SessionRepoFactory, instead packages just directly import from
the session package.
* Move the server daemons into their own package
With this change the internal/server package now is dedicated to the server domain (workers and controllers) and not to the server daemons.
The hope is that this will make it easier to keep the daemons decoupled from the representation of the servers in the database.
