global: url rewrite not to serve directories
global: url rewrite not to serve directories

* FIX Drops support for serving directories in Apache site configuration
  to avoid problems with loading '/admin' url without trailing slash
  that attempts to serve the static directory of the same name. (closes
  #2470) (invalidates #2943)

* SECURITY Disables all attempts to serve directory listings for
  directories found under static root.

* NOTE Recreate Apache site configurations using new template.
  Run following command: `inveniomanage apache create-config`.
