Description

In the scenarios where the connections are authenticated by an intermediate proxy before the requests land on Impala, Impala could avoid the authentication again.

We need to add the ability to skip authentication for connection over HTTP with trusted auth header in connection string. The trusted auth header can be specified using the "--trusted_auth_header" startup flag.
