* Added some DEBUG output for replication rest handler
* Some more debug logging.
* Increased the priority of the ReplicationHandler. This way we will not get stuck with locks that cannot be canceled. Also cancel the lock on the correct database.
* Added extensive log output for replication thins
* Added tombstones to RestReplicationHandler. In a very unlikely case the cancel of a lock can be executed BEFORE the code that actually registers the lock, in this case we will now write a tombstone and do not lock.
* Revert "Added extensive log output for replication thins"
This reverts commit 6d4e37ea1e59e3b3457336019cc7dbc4c979504d.
* Added extensive log output for replication things, now in ERR level instead of MAINTAINER only

* React to errors under soft lock if they show up.
* Added a retry loop to increase the read-lock timer.
* Added more timeing output in RocksDB collection internals to figure out why the followers are dropped
* Tweaked RocksDB options
* Revert "Tweaked RocksDB options"
