Tamar Ben-Shachar be43c3cf88 error based on user command auth not auth to get CLUSTER_ID
We try to get the CLUSTER_ID before we run the user specified command.
If the user if authenticated, but not authorized (to get the
CLUSTER_ID), let them continue and error based on access to the command
they ran.
