add a new eventscript 01.reclock if the reclock file has been set, then this script will test that the reclock file can actually be accessed. if the file does not exist, or if the attempts to stat the file hangs, the node will be marked unhealthy after the third failed monitoring event and after the tenth failure, ctdb itself will shutdown. (This used to be ctdb commit 2cb04747887674def299e574fccb827c1c3194e7)

eventscripts: Use configured RECLOCK file instead of asking CTDB On cluster where recovery lock file is not being used, asking CTDB daemon is unnecessary overhead. And if CTDB is using recovery file, then changing configuration without restarting is *stupid*.

It won't handle the case where the directory is missing and the recovery lock location is updated at run-time. However, this is a good improvement.
