Removed pkidaemon support of apache instances

Tuesday, 26 April 2016

Please review the attached patch which addresses:

  * PKI TRAC Ticket #2248 - support only tomcat instances
    <https://fedorahosted.org/pki/ticket/2248>

The ability to start, stop , and restart instances was tested using 
systemctl on Fedora 23.

Additionally, the scenario described in the revised man page was tested 
to show that pkidaemon works as advertised.
