[server] replace repository's tasks manager by a scheduler
Repository() does not accept anymore a 'tasks_manager' argument but rather a
'scheduler' argument which is expected to be an instance of sched.scheduler
class. The drop the _tasks_manager attribute of the repository and adjust all
internal usages of it. In particular, in the 'repo_stats' service we do not
export 'looping_tasks' statistics anymore as there's no way to retrieve this
anymore from a web instance.
Closes #17057223.

[server] introduce a scheduler class to run repository "looping tasks"
We just use the sched module from the standard library and introduce a tiny
Python2/3 compatibility layer (more for convenience actually). The "looping"
aspect of tasks (previously in LoopTask class) is re-implemeted as a
`schedule_periodic_task` function. This is a reasonably thin layer as compared
to LoopTask/TasksManager classes. Only the "restart" aspect of LoopTask is no
longer present as I'm not sure it's worth keeping.
The advantage of using this (in addition to eventually dropping our custom
code) is that this scheduler class provides a `run` method that blocks the
process while running tasks in its queue. So we can rely on this to have a
'scheduler' ctl command (see forthcoming patch) that would only run "looping
tasks" without having to implement the "blocking" aspect ourself.

[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).
