zwe command should ignore --trace or --debug flags (sometimes)

[Martin-Zeithaml]

Example - zwe internal config get

Note: zowe.setup.dataset.prefix is not defined and the result should be nothing, but the result contains tracing messages.

/zowe/bin: result=$(./zwe internal config get -c ./zowe.yaml -p '.zowe.setup.dataset.prefix' --trace)
/zowe/bin: echo $result
fs.mkdir paths=["/zowe","/zowe/ws"] fs.mkdir paths=["/zowe","/zowe/ws","/zowe/ws/.env"]

Review all zwe commands, which might be affected as zwe internal config get and update/change the behavior of such command.

One of the solutions is to turn tracing/debugging off when processing the command.
