[etwist] Do not call repository's start_looping_tasks anymore and warn about this
We are about to drop this method from Repository class and replace it by a
blocking alternative. This is not compatible with how things currently work in
a Twisted server implementation. So do not start repository "looping tasks" in
Twisted server anymore and issue a warning about this.
If someone is interested in restoring the "all-in-one" behavior where the
repository runs within a Twisted server, they may start by implementing
repository looping tasks using a Twisted mechanism such as, e.g.,
http://twistedmatrix.com/documents/current/core/howto/time.html and eventually
provide the repository with a compatible scheduler instance so that is can
register its periodic tasks. At the moment, we lack resources to do this (and
maintain the Twisted server of CubicWeb in general).
