DTM rest api doesn't return a valid json string

[Chris Zhu]

When there are some TM processes down, the dtmci will show the following:

DTMCI > status tm
Node LeadTM State SysRec ShutdownLevel Incarn Txns IsolTM RMs
0 true UP END RUNNING 3 0 false 0
,1 false UP END RUNNING 3 0 false 0
,2 false UP END RUNNING 3 1 false 0
,3 false UP END RUNNING 3 0 false 0
,4 TM process down. Returned error: 82
,5 false UP END RUNNING 3 0 false 0
,6 false UP END RUNNING 3 0 false 0
,7 false UP END RUNNING 3 0 false 0
,8 TM process down. Returned error: 82
,9 false UP END RUNNING 3 0 false 0
,10 false UP END RUNNING 3 0 false 0

I use rest api to check dtm status, but I don’t think the output is a valid json string.

Added a new state for dtmci to handle all error situations when a response is not received by the TM. So far, these errors are handled as a NOT RUNNING state for the TM. Display in json format has been corrected.
