restart dirsrv as part of ipa-adtrust-install

We should restart Directory Server when performing AD trusts configuration
to enable new CLDAP plugin and force KDC to notice MS PAC is now available.
Previously we only restarted KDC but if dirsrv is restarted, KDC will notice
its socket disappeared and will refresh itself
