IMPALA-10779: Print the username closing a session or cancelling a query from
the WebUI
This patch appends the username of the client who made the request to
close a session or cancel a query from the coordinator's debug WebUI.
Tests:
- Added a new fe test for LDAP auth to verify that the new status gets
printed in runtime profile and coordinator log when a query is
cancelled in this way.
