Title: [WIP] Adding Google Drive

This is work in progress. I'm not too sure with the authentication part... will work on that...

### Other notes
I added a interface for clients. We may want to create a `ClientProvider` of some kind. One may also want to simplify the configuration. (But this is out of scope for this PR)
