When we had cellsv1, we had two different sets of
[Host|InstanceAction|ComputeCells]API. Now that cellsv1 is gone, we only
need nova.compute.api.API, .HostAPI, and .InstanceActionAPI. This patch
removes the dynamic loader shims from nova/compute/__init__.py and swaps
out all references to directly access the classes in nova.compute.api.
Note that there are a couple of ways we could have done this. One way
would have been to replace
from nova import compute
with
from nova.compute import api
and then change
self.compute_api = compute.API()
to
self.compute_api = api.API()
However, the current approach was preferred because
- smaller delta
- the code reads better as compute.API(), which is more important than
the import being pretty
