LP#1691473 Internal Apache HTTP port configuration

Adds an optional new Apache/mod_perl configuration variable for defining
the port Apache listens on for HTTP traffic.  This resolves an issue
where added content lookups attempting HTTP requests on the local Apache
instance on port 80 failed because Apache was using non-standard ports.

To test:

[1] Set a value for OILSWebInternalHTTPPort that's not "80".
[2] Restart/reload Apache
[3] Load a record detail in the catalog
[4] Confirm opensrf logs show:

"tpac: added content connecting to <ip-address>:<new-port> / <hostname>

<new-port> should be the value configured for OILSWebInternalHTTPPort.

+Apache Internal Port Configuration Option
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Apache configuration now supports a new variable which allows admins to
+specify the port used by Apache to handle HTTP traffic.  The value is
+used for HTTP requests routed from Perl handlers back to the same Apache
+instance, like added content requests.  Use this when running Apache
+with a non-standard port, typical with a proxy setup.  Defaults to "80".
