Allow Push to be Authenticated by OAuth2 Token
### Description Similar to gitlab-ce#18106, it would be nice to be able to authenticate a push using the oauth2 token. Right now the only remote git operations that can be authenticated using an oauth token are clone and fetch. This is a feature of both GitHub and Bitbucket. ### Example ``` git remote -v origin https://oauth2:xxxxxxxxxxxxxxxx@gitlab.com/<namespace>/<projectName>.git (fetch) origin https://oauth2:xxxxxxxxxxxxxxxx@gitlab.com/<namespace>/<projectName>.git (push) git push origin master // successfully push having authenticated with the oauth2 token ``` ### Links / references Similar feature request for `gitlab-ci-token`: https://gitlab.com/gitlab-org/gitlab-ce/issues/18106
