[Feature Request] Add alternative auth methods while adding remote models

[AvalakhGit]

Good Day!
It would be great if you could add additional authentication methods for the process of importing a model from a remote repository. For example, using the HTTP Access token for Atlassian Bitbucket.
Directly implementing the command:
"git clone -c http.extraHeader='Authorization: Bearer <_HTTPAccessToken_>' https://bitbucket-server.com/scm/Arhi/archi-model.git"

Not a priority right now, and depends on implementation in JGit. See eclipse-jgit/jgit#94
