Refactor that focuses on SRP improvements

See merge request gitlab-org/gitlab-shell!214

The /api/internal/allowed endpoint on GitLab has been updated to return some
custom git options that can be used with git commands, we need to pass these received options to Gitaly.

Release v8.1.0

See merge request gitlab-org/gitlab-shell!219

Add Git protocol v2

See merge request gitlab-org/gitlab-shell!217

* Use gl_id when we don't know if it's a key-X or user-X
* Use Actor.new_from(gl_id) which will figure out if it's a Key or User
* Use key_str when we're referring to key-X as key_id is confusing

Release GitLab Shell v8.0.0

See merge request gitlab-org/gitlab-shell!218

Add support for ssh certificates

Closes gitlab-ce#34572

See merge request gitlab-org/gitlab-shell!207

- Is possible that gl_id could be a 'user_id'
- Is a more accurate variable name

* Move gitaly, git-lfs and 2FA logic out from gitlab_shell.rb
* Streamline parsing of origin_cmd in GitlabShell
* Utilise proper HTTP status codes sent from the API
* Also support 200 OK with status of true/false (ideally get rid of this)
* Use HTTP status constants
* Use attr_reader definitions (var over @var)
* Rspec deprecation fixes

* Use constants for git commands
* private instead of protected

* Remove HTTP related requires
* Make protocol = GL_PROTOCOL the default

* Rename actor to key_id
* protected to private
* Move attr_reader defintions under private
