This changes the pagination of the "Explore" pages so they use a simpler
pagination system that only shows "Prev" and "Next" buttons. This
removes the need for getting the total number of rows to display, a
process that can easily take up to 2 seconds when browsing through a
large list of projects.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/27390

The compiler needs to be pinned to c++11, which is done by
https://github.com/brianmario/charlock_holmes/commit/51d8a2f0eb1e9d3e476482727d4122b3d11b2bc6

Without this patch it won't install charlock_holmes on newer compilers.

GDK pipeline is failing with this error:
```
Downloading rubocop-rspec-1.15.1 revealed dependencies not in the API or the
lockfile (rubocop (>= 0.42.0)).
Either installing with `--full-index` or running `bundle update rubocop-rspec`
should fix the problem.
```
Updated lockfile by running the bundle update.

`gdk install` works now.
