Parallelize LURemoveInstance

Using the new add/remove infrastructure this becomes pretty easy! :)

Parallelize LUCreateInstance

Finally, instance create on different node, without iallocator, can run
in parallel. Iallocator usage still needs all nodes to be locked,
unfortunately. As a bonus most checks which could have been moved to
ExpandNames, before any locking is done....

Implement adding/removal of locks by declaration

With this patch LUs can declare locks to be added when they start and/or
removed after they finish. For now locks can only be added in the
acquired state, and removed if owned, and added locks default to be...

LockSet: forbid add() on a partially owned set

This patch bans add() on a half-acquired set. This behavior was
previously possible, but created a deadlock if someone tried to acquire
the set-lock in the meantime, and thus is now forbidden. The
testAddRemove unit test is fixed for this new behavior, and includes a...

Now that is_owned is public we don't need to play games at the end of an
LU. If we're still owning anything we just release it.

Add GanetiLockManager.is_owned function

This is a public version of the private function we already had.
We don't just change the previous version because it had lots of users
in the library itself and in the testing code.

Fix LockSet._names() to work with the set-lock

If the set-lock is acquired, currently, the _names function will fail on
a double acquire of a non-recursive lock. This patch fixes the behavior,
and some lines of code added to the testAcquireSetLock test check that...

Add gnt-instance (start|stop) --submit

Finish the --submit changes with these two, which (because they are
multi-opcode commands) require special handling.
