apache frontends: move directives to global conf

https://trello.com/c/RF3kubpI/428-remove-unnecessary-directives-from-frontend-vhost-definitions-enterprise

Move configuration directives out of the front end templates so that
they don't have to be re-created (requiring an outage) if there is a
need to modify them:

    ServerAdmin
    SSLProtocol
    SSLHonorCipherOrder
    SSLCipherSuite
    ProxyTimeout
apache frontends: refactor logging conf, includes

https://trello.com/c/RF3kubpI/428-remove-unnecessary-directives-from-frontend-vhost-definitions

apache-vhost confs had logging directives inline; these were extracted
to a single logging conf file, which admins can modify if they see fit.
Additionally, "Include" directives allow the admin to create an extra
custom conf file that all vhosts will include, completely separate from
anything OpenShift lays down, to minimize the need for modifying files
OpenShift does lay down.
