Support specify id to create a port

Registered by Brin Zhang

When launching many instances (100 to 200) in parallel on a physical small-medium scale cluster (20-30 compute nodes), Nova sees timeouts from Neutron and fails to clean the ports. This leads to Nova instances having multiple ports instead of one.

Add ID to port create, when you create a instance allocation port, you can specify port_id to create a port. If you retry multiple times, query the port information according to port_id firstly, to avoid multiple instances of instance.
