Based on http://docs.openstack.org/mitaka/config-reference/firewalls-default-ports.html
3000 should be unused so far. IANA has assigned 3000 and there is
widespread use colliding with it as well, but neither looks like
something that would collide in Undercloud:

hbci               3000        tcp    HBCI
[Kurt_Haubner]                                        [Kurt_Haubner]
hbci               3000        udp    HBCI
[Kurt_Haubner]                                        [Kurt_Haubner]
remoteware-cl      3000        tcp    RemoteWare Client
[Tim_Farley]                                          [Tim_Farley]

                                                    This entry records
an unassigned but widespread use
remoteware-cl      3000        udp    RemoteWare Client
[Tim_Farley]                                          [Tim_Farley]

                                                    This entry records
an unassigned but widespread use

So by the quick look the 3000 is likely as bad choice as any
unassigned for it by IANA one.
