Convert more kasp test cases to pytest

Convert more kasp test cases to pytest

These test cases follow the same pattern as many other, but all require
some additional checks. These are set in "additional-tests".

The "zsk-missing.autosign" zone is special handled, as it expects the
KSK to sign the SOA RRset (because the ZSK is unavailable).

The kasp/ns3/setup.sh script is updated so the SyncPublish is not set
(named will initialize it correctly). For the test zones that have
missing private key files we do need to set the expected key timing
metadata.

Remove the counterparts for the newly added test from the kasp shell
tests script.
