The common rpc and exceptions were rehomed into
neutron-lib with [1]. This patch shims those rehomed
modules in neutron to switch over to neutron-lib's
versions under the covers.
To do so:
- The rpc and common exceptions are changed to
reference their counterpart in neutron-lib effectively
swapping the impl over to neutron-lib.
- The fake_notifier is removed from neutron and lib's
version is used instead.
- The rpc tests are removed; they live in lib now.
- A few unit test related changes are required
including changing mock.patch to mock.patch.object,
changing the mock checks for a few UTs as they don't
quite work the same with the shim in place.
- Using the RPC fixture from neutron-lib rather than
that setup in neutron's base test class.
With this shim in place, consumers are effectively using
neutron-lib's RPC plumbing and thus we can move consumers
over to neutron-lib's version at will. Once all
consumers are moved over we can come back and remove
the RPC logic from neutron and follow-up with a consumption
patch.
