**Problem**

We expose participants that the current user cannot see because we
don't provide the current user as an argument to participants method
in GraphQL. When the user is missing, then we use the author of the
issuable permissions to fetch participants.

**Solution**

Remove the feature flag to enable verification for participants

The #component_matches_git_sha? runs a git command to see if the
component is at the correct version. To run it, it uses
Gitlab::Popen, but as a side-effect it creates the directory before it
runs the command. This causes the rake task gitlab:gitaly:clone to
incorrectly determine if a git-clone(1) is needed.

To speed things up, and avoid creation of an empty directory, this
change adds an additional check to see if the component's folder exists
anyway.

GraphQL: Limit the amount of ids loaded when using package build infos

See merge request gitlab-org/gitlab!75672

For single package GraphQL queries.
This is achieved by using:
* a custom connection extension that will pass the pagination parameters
to the resolver
* a custom resolver that will read the pagination parameters and load
the right amount of build info objects

The way Gitaly is built in source installations, local test, and CI are
slightly different. In a future commit gitlab:gitaly:install will no
longer be used, but we still need to clone and checkout the correct
revision. To do so, this change extracts the cloning and checking out
into a separate Rake task. The install task will depend on that new task
so that functionality remains the same.

Doing git-fetch(1) to get an object by ID might fail when the git
repository is a shallow clone. To make sure, even older versions of, git
is able to pull those in, configure the repository to use git protocol
version 2.

In several places we need to expand the path from the root of the
project. To simplify this, a helper method is added that expands the
given path to an absolute path.

There is a predefined method for the directory where Gitaly's Gemfile
is, so use that instead.
