Re-implement novaclient bits removed in 10.03.14.2

a)

/os-floating-ips was removed in Compute API 2.36 and from novaclient's
Python API in 10.0

Add to api.computev2:
floating_ip_add()
floating_ip_remove()

Convert add floating IP command to nova-net/neutron split:
"server add floating ip"
"server remove floating ip"

b)

/os-hosts was removed in Compute API 2.43 and from novaclient's
Python API in 10.0.

Add to api.computev2:
host_list()
host_set()
host_show()

Convert host commands to use intenal api:
"host list"
"host set"
"host show"

c)

The introduction of the Network-style commands into the server group
broke cliff's autoprogram directive as it executes the get_parser() methods
without fully initializing the Command object.

NOTE: This is really three reviews squashed to get through the gate in one pass.

Closes-Bug: #1745795
