This adds the methods prepend_if_ee, extend_if_ee, and include_if_ee
that can be used to inject EE specific modules in EE.

These methods are exposed as an initializer that is loaded as soon as
possible. For tests that use fast_spec_helper.rb we must load this
initializer manually, as the Rails environment is not loaded. This is
not the most pretty setup, but unfortunately there is no alternative
that we can use.

1. The output isn't great. It can be hard to find hotspots and, even
   when you do find them, to find why those are hotspots.
2. It uses some jQuery-specific frontend code which we can remove now
   that we don't have this any more.
3. It's only possible to profile the initial request, not any subsequent
   AJAX requests.

Otherwise certain machines return IPv6 first, which is non-deterministic

Rather than relying on NoMethodError deep inside faraday

This means we have one less Net::HTTP monkeypatch.

sham_rack cannot handle IPv6 addresses which means it breaks Net::HTTP
connections because it monkey-patches Net::HTTP
