Alyson Deives Pereira c6a41c20a9 Add ZeroMQ RPC backend 
This feature adds a new RPC backend for communication between
sysinv-api, sysinv-conductor and sysinv-agent processes.
This backend is implemented using a patched zerorpc library [1],
which is built on top of ZeroMQ and message-pack.
The motivation behind this change is to decouple sysinv from RabbitMQ,
and use a brokerless solution for RPC instead.

The key points are:
- All imports of rpcapi.py are replaced by rpcapiproxy.py, which
  decides the backend to use (rabbitmq or zeromq) according to
  configuration.
- During an upgrade process the rpc service listens to both rabbitmq
  and zeromq. For communication between hosts, the client backend api
  is chosen according to host software version.
- In future versions, the usage of RabbitMQ will no longer be
  necessary and its usage can be removed. I have marked these parts of
  code with "TODO(RPCHybridMode)" to easily track it.

TEST PLAN:
PASS: Bootstrap and host-unlock on AIO-SX, AIO-Duplex, Standard
PASS: Bootstrap and host-unlock on DC system-controller and subcloud
PASS: Verify sysinv.log and confirm no error occurs in RPC communication
PASS: Perform system cli commands that interacts with sysinv RPCs:
  - system host-cpu-max-frequency-modify
  - system license-install
  - system storage-backend-add ceph-external
  - system host-swact
PASS: Backup & Restore on AIO-SX
PASS: Bootstrap replay (updating mgmt and cluster subnet) on AIO-SX
PASS: Platform upgrade on AIO-DX (22.06 -> 22.12)
PASS: Platform upgrade on AIO-DX+ (22.06 -> 22.12)
PASS: Platform upgrade on AIO-SX (22.06 -> 22.12)
