Rename references to compute floating IPs client

The single network client is being split out into multiple
clients, one of which will be called FloatingIpsClient. This patch
renames references to the compute floating ips client (floating_ips_client
changed to compute_floating_ips_client) to avoid confusion or conflicts
with the new neutron floating IPs client in code that will reference both
the nova and neutron floating IPs clients.

Partially implements blueprint consistent-service-method-names
