feat: mTLS with client certificate (#3302)

* Support mTLS with client certificate when configured.

* Fix the omitempty typo.

* Add check for missing cert as well.

* Added documentation for artifactory and upload, as well as how to run mkdocs locally

* set pip version to just 3.

* Added example to the full config.

* Remove the Pipfile and update documentation to mention the task.

* update language in doc about multiarch images.
