Mathieu Gagné 386812e287 Add sync_power_state_pool_size option
The sync_power_state_pool_size option allows to set
the number of greenthreads available for use to sync power states.

It can be used to reduce the number of concurrent requests
made to the hypervisor or system with real instance power states
for performance reasons.
