TeamDrive functionality

[tonyOreglia]

The branch works for scripts sitting in a Team Drive by adding the parameter supportsTeamDrives to the upload request.

• Moving the google apps script to a team drive causes https://github.com/danthareja/node-google-apps-script to fail uploading
• This is because google expects a parameter supportTeamDrives set to true, see https://developers.google.com/apis-explorer/?hl=en_US#p/drive/v3/drive.files.update and https://developers.google.com/drive/v3/reference/files/update
• https://developers.google.com/drive/v3/web/enable-teamdrives : “If your application isn't affected by the behavioral differences, then you only need to include thesupportsTeamDrives=true query parameter in requests. This is an acknowledgement that the application is aware of behavioral differences of files contained in Team Drives.”
• Adding supportsTeamDrives: true to

        .then(function(auth) {
          var drive = google.drive({ version: 'v2', auth: auth });
          var options = {
            fileId: id,
            supportsTeamDrives: true,
            media: {
              mimeType: 'application/vnd.google-apps.script+json',
              body: JSON.stringify({ files: files })
            }
          }; ```
  

fixes the problem for a team drive

I've added this as an addition option. I.e.

gapps push --teamdrive

Fixes #61

Code: LGTM but could you please change the README in order to:

• Include the new option under the Docs section for the upload command.
• Add a item in the Common Issues section with your comments about Team Drive
• Fix conflicts :)

Clean this ? :)

How about editing the message that shows up when uploading (something like "Pushing back up to Google Drive (target project is inside a Team Drive)..."?

Won't say better than @lricoy comment about updating the README
