  was:
All keys ends with *:*  adding the same in *Log Aggregation Status* for consistency


     Issue Type: Bug  (was: Improvement)
        Summary: AppBlock page key update and diagnostics value null on recovery  (was: AppsBlock page keep key consistent)


In {{RMAppImpl}} during recovery diagnostics is set as below

{{RMAppImpl#recover(RMState state)}}
{code}
this.diagnostics.append(appState.getDiagnostics());
{code}
So null gets appended to diagnostics;
AppBlock checks for null but value is string 'null'
