feature: Ability to output in `json` from `ibc-setup`

[Anmol1696]

Overview

Inorder to use ts-relayer as a standalone relayer like hermes, it might make sense to have additional flag of --output <json | yaml | default> for all the queries with ibc-setup *.

Why

To be able to use jq with ibc-setup directly in bash instead of having to create a custom wrapper around the relayer. This will reduce the overhead of running the relayer with the current opperators as well (moving ts-relayer to more production usecases).

Will be a nice to have

I agree, this would be a nice improvement. I don't have time for this now, but happy to review and approve a pr

Cool, will try to get this done.

Hmmm... looks like there is no abstraction here, just some console.log stuff. Happy if you make all those lines in inc-setup if statements for two outputs. No need to auto-generate them from some meta-format.

Also, note the verbose/debug logs will always be the same. You can just turn down log level for scripts (via -q), so you only get the final (JSON) output.
