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....

locking.LockSet: Implement acquire timeouts

The timeout passed to LockSet.acquire() is measured over all lock acquires. If
LockSet.acquire fails to acquire all requested locks within the specified
amount of time, all locks are released again and the acquire fails....

Using the new --timeout option:

- gnt-instance shutdown is changed to accept a timeout
- the opcode is changed to hold one
- the LU is changed to optionally get one
- the rpc is changed to carry one
- the backend is changed to take it as a parameter rather than...

ChrootManager: clean StopInstance

Currently it has lots for duplicated code, and internal retries.
Clean it up with the following assumptions:

We'll probably be called more than once.
It is ok to fail to stop, unless we're called with force=True.
If we're called only once, and with force=True it's ok not to run the...

KVMHypervisor: use the StopInstance retry feature

Since we know StopInstance is going to be called more than once (at
least twice, once with force and once without, but normally quite a lot
more) we don't need our own sleep/loop, and we can just send one monitor...

backend.InstanceShutdown: small cleanup

1) unhardcode the timeout, abstracting it in a constant
2) Use time.time() rather than hiding the timeout in a range()
3) call hyper.StopInstance multiple times
-- currently all hypervisors just ignore all calls but once...

Add default instance shutdown timeout constant

It reflects the "current" two minutes we give to the instance.
