Reverted floating-ip-pool UUID sending to Savanna

This needed for https://review.openstack.org/#/c/55978/

HEAT uses neutronclient and this client raises "NeutronClientException: Invalid input for floating_network_id. Reason:
'public' is not a valid UUID." when template contains network_id 'name' instead of UUID.

Also fixed typo in Floating IP label
