Balazs Gibizer edeeaf9102 Add late server group policy check to rebuild 
The affinity and anti-affinity server group policy is enforced by the
scheduler but two parallel scheduling could cause that such policy is
violated. During instance boot a late policy check was performed in
the compute manager to prevent this. This check was missing in case
of rebuild. Therefore two parallel evacuate command could cause that
the server group policy is violated. This patch introduces the late
policy check to rebuild to prevent such situation. When the violation
is detected during boot a re-scheduling happens. However the rebuild
action does not have the re-scheduling implementation so in this case
the rebuild will fail and the evacuation needs to be retried by the
user. Still this is better than allowing a parallel evacuation to
break the server group affinity policy.

To make the late policy check possible in the compute/manager the
rebuild_instance compute RPC call was extended with a request_spec
parameter.
