Code Issues Proposed changes

Correct the IPv6 address and port parsing

Browse Source 
There can be lot of possibility for IPv6 address with port,
for example [::1]:80 or [2001:db8:85a3::8a2e:370]:7334.

Parsing that in more standard way is provided by oslo_uilts.netutils
parse_host_port() method[1].

Also unquote '[]' the SERVICE_HOST in case of IPv6 case so that
DB can listen on correct address.
