Remove unused .contributed-projects class

While working on #13401 and trying to add a new tab to the user profile
page, I came across this. I noticed that the `contributed-projects`
class was only being used in order to select the div in the tests. For
consistency with the other tabs, I decided to remove this class and use
the div's id for the selector.

Limit the number of merge requests per project to avoid long seeds in development environment

This step was taking a long time because seed_fu creates N / 2 merge requests for each repo, where N is the number of branches for that repo. At the time of this writing, there are 234 branches on the gitlab-ce repo, leading to 117 merge requests.

Documentation fix in CI SSH keys setup

In recent versions of Docker, the `/.dockerinit` file doesn't exist any more when running inside a container. That file is used in the example here to detect whether the runner is running inside Docker or not. Change it to check for the existence of `/.dockerenv`, which does exist in all current versions of Docker.

Use 'exec' in Unicorn and Sidekiq launch scripts

When running Unicorn or Sidekiq in the foreground this change removes
an intermediate /bin/sh process. This makes process supervision in the
GitLab Development Kit more reliable.

This change does not affect Omnibus-GitLab (because there we do not
use these launch scripts). Installations from source do use the launch
scripts but for the standard GitLab init script this change will not
make a difference.

Custom installations using Upstart or Systemd may be affected however,
because under certain configurations these systems count exactly how
many forks happen during process startup, and we are reducing that
number by one here.

Closes https://gitlab.com/gitlab-org/gitlab-development-kit/issues/116

Use Rugged's TagCollection#create instead of gitlab-shell's Repository#add_tag for better performance

This was originally opened at !1757 by @pcarranza but I changed it to use Rugged instead of gitlab_git, following @DouweM's request.

Once this is merged, https://gitlab.com/gitlab-org/gitlab-shell/merge_requests/26 will be mergeable too.

Fix typo in user steps feature file

Just came across a typo in the user steps file.

See merge request !3943

Update patch_versions.md with explicit --with statement for db gem group

## What does this MR do?
Updates `patch_versions.md`'s instructions on installing gems to explicitly install either the postgres or mysql groups.

## Are there points in the code the reviewer needs to double check?
No, but thank you for your time.

## Why was this MR needed?
I performed the steps listed in `patch_versions.md` and ran the command for updating postgres gems. Bundler told me at the end that it had not installed the postgres gem group, which caused the next step, migrating the DB, to fail for obvious reasons.

Changing the command to `--with postgres` made it install the postgres gem group, and db:migrate then passed.

## What are the relevant issue numbers?
None

## Screenshots (if relevant)
N/A

Since `User#to_param` already returns `User#username`, we don't need to
