Fix proxy and redirect configuration file names.

While working on puppet-lodgeit acceptance tests we found that the
configuration file that `httpd::mod::proxy` creates was not being picked
up by Apache because it was missing the prefix `.conf`. This transition
is required to configure httpd modules correctly on Apache >= 2.4

To prevent Apache from loading two the same configuration twice, we
remove the file without extension, so this change does not affect
running systems.

This change has fixes for `httpd::mod::proxy` and `httpd::mod::redirect`
as they have the same issue. We added tests as well to increase the
confidence on the fix.

The acceptance will be fixed on the follow-up patch, as the redirect
grants are broken for 2.4 as well.
