Fix elasticsearch global code search following https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9655

There were 3 problems with sticking:

1. When sticking to a request (based on a previous request) we would
   always overwrite the WAL pointer, leading to a user being stuck to
   the primary for too long.

2. Sticking was not working for the Grape API. The API in particular is
   tricky because we have to stick either using a user, CI runner, or a
   CI build.

3. Refreshing of permissions did not lead to the refreshed users being
   stuck to the primary. This could result in users not being able to
   access new resources for a brief moment of time, or them still being
   able to see old resources.

To solve this some of the Grape related logic is handled by injecting EE
specific modules in the right places. This ensures we can stick as early
as possible, using the right data. The same technique is applied for
various parts of the CI codebase.
