[OVN] Off-path SmartNIC DPU Port Binding with OVN
Traditionally it has been the CMSs, in OpenStacks case Nova's,
responsibility to create Virtual Interfaces (VIFs) as part of
instance life cycle, and subsequently manage plug/unplug operations
on the Open vSwitch integration bridge.
With the advent of SmartNIC DPUs which are connected to multiple
distinct CPUs we can have a topology where the instance runs on one
host and Open vSwitch and OVN runs on a different host, the
SmartNIC DPU control plane CPU.
One of the main use cases for having this topology is security
where we treat the hypervisor host as untrusted and prohibit
direct communication between the hypervisor host and the SmartNIC
DPU control plane host. In addition to that control facilities
such as switchdev devices are only visible from the SmartNIC DPU
control plane CPUs.
Adds support for binding ports of type VNIC_REMOTE_MANAGED by
looking up chassis based on serial number that Nova provides in
the binding_profile.
Information required by the OVN controller to successfully look up
and plug representor port is provided as options on the LSP as
defined by the representor plug provider documentation [0][1].
