[7.x] Clean up ShardFollowTasks for deleted indices (#44702) (#44790) ...

Deleting a follower index does not delete its ShardFollowTasks, potentially
leaving many persistent tasks in the cluster that cannot be allocated on
nodes and unnecessary fill the logs. This commit adds a cluster state listener
(ShardFollowTaskCleaner) that completes (with a failure) any persistent task
that refers to a non existent follower index.

I think that this bug has been introduced by #34404: before this change the
task would have been completed as failed and removed from the cluster state.

Backport of #44702 and #44801 on 7.x
