Code Issues Proposed changes

Nexus MD: Neutron trunk support 

Add neutron trunk support to the cisco_nexus mechanism driver.

For baremetal deployments, the setting of 'switchport...native'
is now set for a trunk's parent port (also the vlan associated
with the trunk's parent port will also be configured as 'allowed').
All other ports (trunk subports) will be set as 'allowed'.

VM deployments nexus switchport setting isn't changed by this patchset.
