Events: Socket creation after getaddrinfo and IPv4 and IPv6 packet capture

Issue: Currently, the socket creation is done
prior to getaddrinfo function being invoked. This
can cause mismatch in the protocol and address
families of the created socket and the result
of the getaddrinfo api. Also, the glustereventsd
UDP server by default only captures IPv4 packets
hence IPv6 packets are not even captured.

Code Changes:
1. Modified the socket creation in such a way that
the parameters taken in are dependent upon the
result of the getaddrinfo function.
2. Created a subclass for adding address family
in glustereventsd.py for both AF_INET and AF_INET6.
3. Modified addresses in the eventsapiconf.py.in

Reasoning behind the approach:
1. If we are using getaddrinfo function then
socket creation should happen only after we
check if we received back valid addresses.
Hence socket creation should come after the call
to getaddrinfo
2. The listening server which pushes the events
to the webhook has to listen for both IPv4
and IPv6 messages as we would not be sure as to
what address family is picked in _gf_event.
