Description

Currently, impersonation is limited to creating batches and sessions with "proxyUser". It would be better to fully support impersonation for all endpoints. This is only possible as a query parameter since many of the endpoints are get requests. Adding support for the "doAs" query parameter matches what Hadoop does. We can leverage the same types of configs as well. This change is backwards compatible since we can check for doAs before proxyUser and use that. This will not remove the proxyUser checking for batch and session creation.
