Make sure python3-novaclient is installed before creating fence_compute
Make sure python3-novaclient is installed before creating fence_compute

This has been observed during an IHA FFU process. Namely
after the OS upgrade by LEAPP the fence_compute resource will
fail starting because python3-novaclient is not installed.
Normally this is taken care of by rpm dependencies, but
fence_compute is buggy and does not explicitely have that
dep (https://bugzilla.redhat.com/show_bug.cgi?id=1857247)

So we need to make sure the package is installed before
creating the resource.

Tested this on four consecutive successful IHA FFU runs
and it worked okay.
