Copy debug level, priority and set comment for LU-generated opcodes

Before this patch, a node evacuation submitted with high priority would
only compute the solution at that priority, but the actual evacuation
ran at normal priority.

Increase the lock timeouts before we block-acquire

This has been observed to cause problems on real clusters via the
following mechanism:

- a long job (e.g. a replace-disks) is keeping an exclusive lock on an
instance
- the watcher starts and submits its query instances opcode which...

Generalize the OpCode-should-be-in-mcpu test

Currently, the unittest TestDispatchTable in mcpu unittest does a
hard-coded approach to test whether an opcode should be included or
not in the mcpu.Processor dispatch table. This is not flexible, so we
replace it with two changes:...

mcpu: Adjust lock acquire strategy

The changes to job queue processing require some changes on this class'
interface. LockAttemptTimeoutStrategy might move to another place, but that'll
be done in a later patch.

mcpu: Change lock attempt timeout calculation

With this patch all timeouts are pre-calculated. The interface of
the _LockTimeoutStrategy class is also changed a bit; NextAttempt
now returns a new instance.

mcpu: Implement lock timeouts

The timeout is always between ~0.1 and ~10.0 seconds. A small
variation of ±5% is added to prevent different jobs from
fighting each other. After 10 attempts to acquire the locks with
a timeout, a blocking acquire is made.

Lock status reporting will be improved in a separate patch....
