ipatest: add test for ipa-pkinit-manage enable|disable
Add a test for ipa-pkinit-manage with the following scenario:
- install master with option --no-pkinit
- call ipa-pkinit-manage enable
- call ipa-pkinit-manage disable
- call ipa-pkinit-manage enable
At each step, check that the PKINIT cert is consistent with the
expectations: when pkinit is enabled, the cert is signed by IPA
CA and tracked by 'IPA' ca helper, but when pkinit is disabled,
the cert is self-signed and tracked by 'SelfSign' CA helper.
The new test is added in the nightly definitons.
