Implements the feature requested in gitlab-org/gitlab#19672

This requires the internal api counterpart in gitlab-org/gitlab!36302 to
be merged first.

It can be used as follows:
```
censored@censored-VirtualBox:~/git/gitlab$ ssh git@gitlab-2004 personal_access_token
remote:
remote: ========================================================================
remote:
remote: Usage: personal_access_token <name> <scope1[,scope2,...]> [ttl_days]
remote:
remote: ========================================================================
remote:

censored@censored-VirtualBox:~/git/gitlab$ ssh git@gitlab-2004 personal_access_token newtoken read_api,read_repository 30
Token:   aAY1G3YPeemECgUvxuXY
Scopes:  read_api,read_repository
Expires: 2020-08-07
```

Generate and log correlation IDs

This will make it easier to tie an SSH access request to Rails API and
Gitaly requests.

Log SSH key details

See merge request gitlab-org/gitlab-shell!398

Stan Hu authored 4 years ago and Igor Drozdov committed 4 years ago

Right now when a client such as gitlab-shell calls the
`/api/v4/internal/allowed` API, the response only tells the client what
user has been granted access, and it's impossible to tell which deploy
key/token was used in the authentication request.

This commit adds logs for the following when available:

1. `gl_key_type` (e.g. `deploy_key` or `key`)
2. `gl_key_id`

These fields make it possible for admins to identify the exact record
that was used to authenticate the user.

API changes in the `/internal/allowed` endpoint in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/37289 are needed
to support this.

Log remote IP for executed commands

Closes #199

Drop Go v1.12 support

See merge request gitlab-org/gitlab-shell!401

We officially use Go v1.13+ for everything
(https://docs.gitlab.com/ee/install/requirements.html#go-versions), and
dropping Go v1.12 allows us to use new methods such as
`http.NewRequestWithContext`.

Admins may want to know what client IP originated the request. This
commit adds a `remote_ip` field to the log that extracts the IP address
from the `SSH_CONNECTION` environment variable.

Use simplified setup for code intelligence

Use codequality CI template

See merge request gitlab-org/gitlab-shell!389

In https://gitlab.com/gitlab-org/gitlab/-/issues/218797, it was
determined that gitlab-shell is using an outdated image that no
longer exists.

To ensure that we are using up to date codequality image, we
can use the built-in template instead.

Upgrade Ruby version to v2.6.6

GitLab has now been upgraded to use Ruby 2.6.6:

Use default puma socket in example config

See merge request gitlab-org/gitlab-shell!388

The unicorn replacement 'puma' uses a unix socket in the example config [1] instead of a tcp port.
Using the non-existing tcp port results in "Internal API unreachable" on
git operations.

Fix race conditions with logrus testing

Closes #450

Add race testing as separate CI step

See merge request gitlab-org/gitlab-shell!383

Release v13.2.0

See merge request gitlab-org/gitlab-shell!384

logrus fires a Goroutine to write logs, so the tests could fail if they
checked the event queue before the logrus have fired.  Since there isn't
an easy way to flush all outstanding hooks, we just retry every 100 ms
for up to a second for log to arrive in the queue.

Closes https://gitlab.com/gitlab-org/gitlab-shell/-/issues/450
