Support floating ip associate/disassociate

[hongbin]

Right now, OSC has the following commands:

  server add floating ip Add floating IP address to server
  server remove floating ip Remove floating IP address from server

These commands only work for Nova but couldn't work in general (i.e. add floating ip to Kuryr-enabled container). This bug suggested to bring the following Neutron commands to OSC:

  floatingip-associate Create a mapping between a floating IP and a fixed IP.
  floatingip-disassociate Remove a mapping from a floating IP to a fixed IP.

I was also hit an error with following command:

$ openstack server add floating ip demo1 $(openstack floating ip create public1 -f value -c floating_ip_address) --debug
