add -trace

[ppadmavilasom]

Request to add -trace global flag so intermediate command results in a pipeline sequence can be displayed for debugging.
It might even be good to make this a config to turn on and off without modifying test scripts

for eg if we run

tcli utils echo -format 'range(1;2) | {body: {id:.,name:.|tostring,photourls:[.|tostring]}}' \
  | tcli petstore pet addPet  

we get something like

{“id”:1,”name”:”1”,photoUrls”:[],”tags”:[]}

however, to still keep the pipeline and see intermediate output of what was provided as body to add, something like the following is needed

tcli utils echo -format 'range(1;2) | {body: {id:.,name:.|tostring,photourls:[.|tostring]}}' | tee /tmp/body;tcli petstore pet addPet  < /tmp/body

now we get something like

{“body”: {“id”:1,”name”:”1”,”photoUrls”:[1]}}
{“id”:1,”name”:”1”,”photoUrls”:[],”tags”:[]}

Ask here is to either do

tcli utils echo -format 'range(1;2) | {body: {id:.,name:.|tostring,photourls:[.|tostring]}}' -trace \
| tcli petstore pet addPet  

or add a flag in config.yaml to turn on trace globally so that intermediate results are visible.
