This patch adds support for requested vnic_type to be plugged to neutron port to ML2 plugin. This patch contains: 1. New attribute 'binding:vnic_type' added to port binding extension. Possible values are 'direct', 'macvtap' and 'normal'. 'binding:vnic_type' is allowed to be defined on port creation or changed on port update by admin or tenant user. 'binding:vnic_type' can be also skipped in port defintion 2. Management of vnic_type by ML2 plugin, assuming default vnic_type=normal 3. Add 'vnic_type' to ml2_port_bindings DB table 4. Add supported vnic_types for MechanismDrivers that are capable to bind port. 5. Add DB migration script for ml2_vnic_type. DocImpact: Need to update portbindings API docs and include in SR-IOV user docs Change-Id: Ic88708fa9ece742f807c1d09bb49e499f99bd092 Implements: blueprint ml2-request-vnic-type
