hlr: pyhss: run the pyhss_hss service

Database preparations used to be done in PyHSS by all services if they
noticed that this was needed. The time between checking and creating the
tables caused a race condition where two services attempting to create
tables at the same time will result at one of them failing, we have seen
this in our ttcn3-hlr-test-pyhss jobs sometimes:

  [Database] [DEBUG] Table apn already exists
  [Database] [DEBUG] Table auc already exists
  [Database] [DEBUG] Table subscriber already exists
  …
  [testenv][pyhss] pyhss_gsup: setup script failed

I have fixed this upstream by letting only the main service (pyhss_hss)
prepare the database:
https://github.com/nickvsnetworking/pyhss/commit/8b8a2202c345fbb7262c9d07d03003cd2fdb819f

This means that we now need to run the pyhss_hss service in the HLR
tests, so pyhss_gsup doesn't fail with:

  [Database] [INFO] Waiting for the main service to prepare the database
  ERROR: 127.0.0.1:4222 did not become available within 5s!
  [testenv][pyhss] pyhss_gsup: setup script failed

{hlr,hss}/pyhss/config: remove unused options

PyHSS had several unused config options. They have been removed
upstream, remove them from the osmo-ttcn3-hacks configs as well.

ggsn: TC_pdp(4)6_clients_interact: Expect UEs can interact using global IPv6 address

The link-local IPv6 address is only meant to be used privately between
the UE and the GGSN, but the UEs should be in general able to reach each
other using their global IPv6 address (unless some operator policy
explicitly forbids it).

Since open5gs.git 6cc627c4855703a17c92352660078325c6ce63cc, open5gs-upfd supports
proper routing of IPv6 packets between UEs.

osmo-ggsn apparently doesn't implement that internal routing logic yet,
so these tests will start failing now, but it's actually legit to have
it not passing the test anymore.

Print load before and after each test

Make it easier to figure out why tests are failing sporadically by
printing the load before and after each test. For example:

  ------ MGCP_Test.TC_crcx_sdp ------
  (14:24:42) load average: 0,41, 0,44, 0,54

hnbgw: Fix regression in hnbgw-test-latest

Fix unintended if condition removal in recent commit when
in the -latest case. That commit expected to leave the -latest path
untouched but ended up removing the line. Re-add it.

hnbgw: Fix race conditions during PFCP Association

Since osmo-hnbgw now sends Heartbeat Requests, we need to take that into
account.
Furthermore, since it also now supports retriggering association when
detecting peer restarted upon rx of Heartbeat Req, use that to trigger
an association to clean up state and have a deterministic way to
synchronize at that point regarding state.

bsc: TC_stat_msc_sctp_disconnected Fix sporadic failure

Since we recently increased a bit the timeout to assume the BSSAP_LE
peer (SMLC) is implicitly up, the function
f_bssap_le_wait_sccp_peer_available() may still be onging when we drop
the sctp connection at the STP in the test, which will generate an
explicit DUNA towards BSSAP_LE and hence fail the test because it never
comes back available before it times out.

Since we don't need nor test SMLC in this test, simply disable starting
the SMLC here to avoid this race condition and simplify the test.

5gc: Split f_start_handler_with_pars() into multiple helpers

This allows initializing multiple ConnHldr and then connecting them and
starting them later. This is similar to what is is done eg. in
MSC_Tests.

BSSAP_LE_Emulation: Increase timeout in f_bssap_le_wait_sccp_peer_available()

It was spotted in SMLC_Tests.ttcn that the current timeout may be too
short, and the test fails because ttcn3 connects to STP and receives a
DUNA, and then the IUT (osmo-smlc) connects to STP around 4 seconds
later, which is too late with existing timeout.
