Fix post deployment hook for /etc/hosts in multi-stack

Add /etc/hosts entries for all cells' nodes on internal_api network
as well. Enable rabbitmq connections from superconductor and
scheduler via transport URLs defined for other cells'.

NOTE: tripleo_stack_name only used in start/end markers by the
tripleo_hosts_entries role. Use a non-conflicting "stack" name
for markers to append to hosts entries created for the overcloud
stack, and stacks created for additional cells.
