Rafael Ávila de Espíndola 27bd3fe203 service: Add a lock around migration_notifier::_listeners ...

Before this patch the iterations over migration_notifier::_listeners
could race with listeners being added and removed.

The addition side is not modified, since it is common to add a
listener during construction and it would require a fairly big
refactoring. Instead, the iteration is modified to use indexes instead
of iterators so that it is still valid if another listener is added
concurrently.

For removal we use a rw lock, since removing an element invalidates
indexes too. There are only a few places that needed refactoring to
handle unregister_listener returning a future<>, so this is probably
OK.

Fixes #5541.
