EE port of https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/17711.

This isn't interesting most of the time and is may go over other flash banners.

These don't have performance data saved as they use Grape.

The problem is this: when each phase starts, it checks if all jobs in earlier
phases are complete. package-and-qa is slow. As build is the first phase, if you
trigger package-and-qa before the prepare phase is finished, the entire test
phase will be blocked until package-and-qa completes, which isn't what we want.

But equally, if build came _after_ test, then package-and-qa couldn't be started
until the tests were finished. Putting it in the same stage as the tests means
we can have our cake and eat it.

Rails 5: replace removed silence_stream

See merge request gitlab-org/gitlab-ce!21387

By default, sidekiq-cluster will allocate N threads for N queues specified
on the command line, which in turn will require N + 5 Redis connections.
Especially when used with the `--negate` flag, this can lead to using hundreds
of Redis connections, which can lead to performance issues.

This change also adds a `-m N` option to cap the number of threads. For each
queue group, the concurrency factor will be set to min(number of queues, N).

Closes #7374
