a217a5d290
Added a new port extension: NUMA affinity policy. This extension adds the "numa_affinity_policy" parameter to the "port" API and specifies the NUMA affinity policy per port. This parameter is passed to Nova when a virtual machine is created. Nova will use this information to schedule the virtual machine. For backwards compatibility, this parameter will be "None" by default. Depends-On: https://review.opendev.org/#/c/740058/ Closes-Bug: #1886798 Change-Id: Ie3d68c098ddb727ab8333aa1de4064e67a4f00a7
