DRILL-6459: Unable to view profile of a running query
Fixes the missing text component of the QueryId that causes lookups to fail in `WorkManager.queries` map.
This got introduced with the fix (#1265) for DRILL-5305
Reverting change to QueryIdHelper and DRILL-5305
Removing the changes done, based on inputs from @vrozov and @sohami . The correct approach would be to have this as part of the profile to avoid serialization of the queryIdText for each RPC making use of the QueryId
UX Changes
Set the query ID string and display in WebUI
closes #1301
