Subject: [PATCH] Restart httpd if ipa-server-trust-ad is installed or updated

If ipa-server-trust-ad is installed after the ipa server is installed
and configured, httpd needs a restart for additional python modules to
be loaded into httpd on IPA initialization.

Fixes https://fedorahosted.org/freeipa/ticket/3185
