request to change REST API's output for (auto)compaction with "/pools/default/tasks" enpoint

Some customer would like the output of a query to the "/pools/default/tasks" endpoint to display compaction related status in a similar way as it is done for rebalance: for compaction, the current behavior is to display status only if (auto-)compaction is running, otherwise nothing shows. For rebalance, there's the "notRunning" status, which shows information even when no rebalance is in progress.

# curl -u Administrator:password http://172.23.96.77:8091/pools/default/tasks | python -mjson.tool

...

 {

 "masterRequestTimedOut": false,

 "status": "notRunning",

 "statusId": "778c14cdb9eac33fe990cf4764ed1e79",

 "statusIsStale": false,

 "type": "rebalance"

 },

...
