Add commands to extract|provision net vips

Add command to extract Virtual IPs information from
a deployed overcloud. This writes a 'vip_data' file
that should be used when managing neutron Virtual IP
resources "outside" the overcloud Heat stack.

Add command to provision Virtual IPs using 'vip_data'
file as input. This command will output a
'vip_environment' file with the resource_registry and
paramters to replace the neutron resources in the
overcloud Heat stack.
