Compute manager to use thread pools selectively ...
This changes the thread pool usage of the ComputeManager to go through
the concurrency mode aware util functions.
The concurrent live migration pool had a seemingly unlimited option
when configured with value 0, but in reality GreenThreadPool has a
default worker size of 1000. In reality it is almost never right to
have more than one live migration running concurrently. Also with
native threading having 1000 worker is just too costly. So we
decided to deprecate the value 0 and changed the implementation of
unlimited to mean 5 threads in native threading mode. We kept the 1000
greenthread in eventlet mode for backward compatibility.
The _sync_power_states periodic task also spawn tasks for each instance
to be synced. As it uses a shared data structure across these tasks
and the caller a lock is needed to avoid race conditions.
Also the default pool size is 1000 for these tasks in our configuration.
That would use a lot of memory on a busy host in native threading mode.
So we changed the default value from 1000 to 5.
