Subject: [PATCH] replica install: improvements in the handling of CA-related
 IPA config entries

When a CA-less replica is installed, its IPA config file should be updated so
that ca_host points to nearest CA master and all certificate requests are
forwarded to it. A subsequent installation of CA subsystem on the replica
should clear this entry from the config so that all certificate requests are
handled by freshly installed local CA.
