Thanks @JoeSL for the PR. This is going to be really useful for the community.

Can you please do the following before we can review the PR:

• Resolve conflicts
• Rename the files, classes and other things from Google Drive Folder to Google Drive? We want to keep the effort low for the users when adding data sources. So, google_drive_folder will become google_drive, GoogleDriveFolderChunker will become GoogleDriveChunker and so on.

Thanks again for this PR.
