The purpose of the various IP addresses used by our GGSN tests is not
immediately clear. Add documentation based on the current status quo.

Various improvements to the comments documenting packet templates
used in GGSN_Tests: fix IPv4 vs. IPv6 confusion, clearly indicate
whether templates are used for sending or for receiving/matching
packets, and add a missing comment.
Found while studying code to prepare for issue OS#2519.

It seems due to the current network configuration, pdp v4 ctx can talk
each other while pdp v6 ctx cannot.

New dependency is required: titan.ProtocolModules.ICMP
It tests that ICMP echo packets can be sent successfully (reply is
received or otherwise dest unreachable if routing is not set up
correctly during the test). It also tests some cases in which osmo-ggsn
is required to drop the packets (eg. unknown src ip unrelated to pdp
ctx). It also checks that IPv6 packets are dropped in IPv4 pdp ctx and
viceversa It also checks that IPv6 packets are dropped in IPv4 pdp ctx
and vice versa.

In commit 0b7545dff1 I accidentially
committed incomplete support for user plane (GTP-U) testing to
the GGSN test.
This code has caused the jenkins tests since August 26th to fail,
let's revert it until this is fully implemented + tested.
