GoogleDriveConnector: Add an automatic retry for HTTP errors

I still run into the issue of the GDrive connector failing and terminating the workspace for failed HTTP errors. For my case these are internal server errors (code 500), stating "Daily Limit for Unauthenticated Use Exceeded". This was explored in this thread, but the issue still exists even with a custom web connection using a Google API key, and the limits (viewed via the drive API console) are nowhere near being exceeded. I believe an automatic retry of failed HTTP requests would fix this issue, as suggested in the drive api guide by including an "exponential backoff".
