Request adding "quotaUser" parameters to by pass per user limit when writing and reading

[zhuylanz]

According to this document from Google: https://cloud.google.com/apis/docs/capping-api-usage#limiting_requests_per_user

To identify a user, use the quotaUser=userID URL query parameter. This value is for short-term quota enforcement only, so you don't need to use a real user ID. You can choose any arbitrary string under 40 characters long that uniquely identifies a user.

So it is possible that we can bypass the limit of request per user by this parameter, can you help to add this options to this package?

Thank you!
