only search for Kerberos SRV records when autodiscovery was requested
When a list of servers is passed to ipa-client-{install,automount} the search
of Kerberos and LDAP SRV records should be suppressed and the specified
hostnames used directly as LDAP servers/KDCs. We thus should not performed
search for KDCs when the autodiscovery was actually not requested.
