Description

We currently use authorization_factory_class flag to switch to a different authorization provider, which is useful for any third party to provide an implementation of authorization provider. Since, Sentry and Ranger are officially supported by Impala, we should have a flag, i.e. authorization_provider=[sentry|ranger] to easily switch between officially supported authorization providers.

At the time of this writing, the existing authorization_factory_class flag is being retained but its default value removed.  If present, it will take precedence over the authorization_provider flag being added.
