Closes gitlab-org/gitlab-ee#3125

Changelog: https://git.io/v5403

Update Prometheus Client MMAP gem to version that fixes performance degradation caused by workers churn

We now manage this dependency in Yarn.

This gem allows Sidekiq jobs to be throttled. Unfortunately, it has a
side-effect: when we haven't enabled job throttling, it will still hit Redis a
lot (and miss, because nothing is configured).

As this setting already required a restart, ensure that the library is only
required when it's enabled.

Backports EE mirror stuck handling feature (https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/2628) to CE

Main feature was the deprication of the Hashie stuff, so the access by
calling keys as method is gone now.

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.
