Enable floating IP on all-in-one setup
Make public urls use public_address in all-in-one

The public url endpoints currently use 127.0.0.1 for their hostname, so
it's impossible to use the all-in-one cloud from outside the host.
Change this to public_address so that it can be tested from the outside.

Update keystone bind_host value to 0.0.0.0

Currently this is configured as 127.0.0.1 which disallows
Identity Service API calls from remote hosts. Updated to
0.0.0.0 so as to allow remote connections but not break
any 127.0.0.1 requests. This is actually the default value
but rather then undef the param I am just changing it.
