Changed the way stats observe returns results
Changed the way stats observe returns results

We now comma seperate all values in order to keep the
protocol consistent with the current stats command.

For example:

--> stats observe watchset1
<-- key1 12 0 replicated,persisted

becomes

--> stats observe watchset1
<-- key1,12 0,replicated,persisted
