Never remove job queue lock in node daemon

Otherwise, corruption could occur in some corner cases. E.g. when
LeaveNode is running in a child and is in the process of removing
queue files, the main process gets killed, started again and gets
a request to update the queue. This is rather extreme corner case,...

Implement master startup safety check

This is an initial version of the master startup checks. It's a very
rudimentary change, however in normal usage (an old master was started,

Parallelize LUReplaceDisks

This is the most complex parallelization so far. We have to lock one
