ci: Misc changes for Unbuntu 20.04

To get the tests to pass in Unbuntu 20.04 a few work arounds were
needed. Over time the workarounds should be removed, but now I need
progress.

* Change how nipapd is started when running the apt tests. From some
  reason the daemon won't start with systemd, so let's just start it
  manually. Also, it by default tries to drop privileges and then
  cannot read some postgres certificate in /root. Thus, avoid dropping
  privileges.

  And yes, the daemon won't start from systemd without dropping
  privileges either.

* Run the CLI tests over plain-text HTTP. With the newer versions of TLS
  libs in 20.04, a CN is not enough but a subject alternative name (SAN)
  is required as well. It's a bit more tricky to generate a cert with
  SAN, so instead I let the CLI tests run over plain-text HTTP instead.
  The REST tests pass over TLS (with warnings regarding missing SAN).

* As the Python 2 version of NIPAP cannot be installed on Ubuntu 20.04,
  the upgrade tests are disabled until we can upgrade from a Python
  3-based version.

* Enabled an "Accident analysis"-step in the CI pipeline. If the test
  fails it's run and gathers some data for debugging.

More debugging
