Description of the problem, including code/CLI snippet

Gitlab API support to attach a file to a wiki page which is nice for bot generating wiki page such as dashboard.
See : https://docs.gitlab.com/ee/api/wikis.html#upload-an-attachment-to-the-wiki-repository

Expected Behavior

Something like proj.wikis.upload(id,file,branch) would be ideal

Actual Behavior

The API is not reflected in python-gitlab

If I am missing something, tell me, but I havent found that API call
