global: url rewrite rule for '/admin' to '/admin/'

* FIX Adds rewrite rule 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)

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