Separate floating_ips_bluk_client

As the qa-spec of consistent-service-method-names, we have decided
all service client modules will be separated into a single module
by each resource. So this patch separates floating_ips_bluk_client
from floating_ips_client.

Partially implements blueprint consistent-service-method-names
