Webserver sometimes needs rewrites to handle deprecated URLs from prior setups/hosting, mistakes etc

Continuing the discussion from [SOLVED] Shortcut for /Calendar and MIT%20Directions:

If we migrate a wiki for acme.com, they may have a URL like acme.com/Calendar that needs to redirect now into their wiki space. If we’re handling the wiki, then we can accommodate with a rewrite in Apache.

:warning: This is deployed on the demo server by @greg and needs to be migrated into the Ansible role before a new deploy can be done without overwriting the Apache configuration.
