We don't use certmonger to get certificates during installation because
of the chicken-and-egg problem. This means that the IPA web and ldap
certs aren't being tracked for renewal.
This requires some manual changes to the certmonger request files once
tracking has begun because it doesn't store a subject or principal template
when a cert is added via start-tracking.
This also required some changes to the cert command plugin to allow a
host to execute calls against its own service certs.
