ipatests: mark known failures as xfail
Commit 5dbcc1a9d30cdb0bc1c4f8476be37a3ef781f9be marked
the base class method test_replica0_with_ca_kra_dns_install
as known failure, but this does not work with inherited
classes. The child class methods need to be marked
themselves as known failures with @pytest.mark.xfail
Furthermore, TestInstallWithCA_KRA2 and TestInstallWithCA_KRA_DNS2
tests should succeed because the master is installed with KRA
(issue 7651 is related to replica install with --setup-kra
when it is the first KRA instance).
