Add checkds system test

Browse Source 
Add a Pytest based system test for the 'checkds' feature. There is
one nameserver (ns9, because it should be started the latest) that
has configured several zones with dnssec-policy. The zones are set
in such a state that they are waiting for DS publication or DS
withdrawal.

Then several other name servers act as parent servers that either have
the DS for these published, or not. Also one server in the mix is
to test a badly configured parental-agent.

There are tests for DS publication, DS publication error handling,
DS withdrawal and DS withdrawal error handling.

The tests ensures that the zone is DNSSEC valid, and that the
DSPublish/DSRemoved key metadata is set (or not in case of the error
handling).

It does not test if the rollover continues, this is already tested in
the kasp system test (that uses 'rndc -dnssec checkds' to set the
DSPublish/DSRemoved key metadata).

The test setup for the checkds tests.
These servers are parent servers:
- ns2 is a primary authoritative server that serves the parent zone for zones
configured in ns9.
- ns4 is the secondary server for ns2.
- ns5 is a primary authoritative server that serves the parent zone for zones
configured in ns9, but this one does not publish DS records (to test cases
where the DS is missing).
- ns6 is an authoritative server for a different zone, to test badly configured
parental agents.
- ns7 is the secondary server for ns5.
Finally, ns9 is the authoritative server for the various DNSSEC enabled test
domains.
