This will prevent subsequent failures from overwriting the verdict so we
can easily see the root cause of the test failure.
Using testcase.stop instead for errors internal to our test
infrastructure to mark them as test errors instead of failed.

When the protocol configuration options (PCO) contain an IPCP container
then lists only one one DNS server (normally there are two included, a
primary and a secondary). Than the parser in osmo-ggsn runs into an
endles loop. This testcase tries to provoke this behavior by sending
PDP CONTEXT ACTIVATE messages with PCO that contain only a single DNS
entry per IPCP container.
The hanging of osmo-ggsn is already fixed (see Depends). However when
Primary and Secondary DNS are in separate IPCP containers, then only
the first IPCP container is parsed (see also OS#3381)

Add VTY functionality to GGSN tests, and use the VTY to enable/disable
GTP-U Tx sequence numbers in the running osmo-ggsn.
The GTPU packet template now makes sequence numbers optional.
A template created with its sequence number set to 'omit' will result in
a packet without a sequence number, i.e. the 'sequence number present' bit
in the packet header is cleared, and the sequence number field is omitted
from the encoded GTPU T-PDU packet.
Re-use the existing TC_pdp4_clients_interact() test for testing the
behaviour of osmo-ggsn. This test is now run twice, once with and
once without GTP-U Tx sequence numbers. Verify that packets relayed by
osmo-ggsn match its "g-pdu tx-sequence-numbers" configuration setting.
