Add callback cli command

[dfarr]

Create a callback associated with a promise.

Commands:

• create

Examples:

resonate callbacks create --promise-id foo --root-promise-id bar --timeout 1h --recv default

A receiver can be either a string or an object, an object must always have a type and data.

• logical as string (eg: "default")
• physical as url string (eg: "poll://default/6fa89b7e-4a56-40e8-ba4e-78864caa3278")
• physical as object (eg: {"type": "poll", "data": {"group": "default", "id": "6fa89b7e-4a56-40e8-ba4e-78864caa3278"}}

See promises and schedules for a reference.

Hey, this project seems interesting. Can I take up this issue to start contributing to this repo?

[dfarr]

Of course! Thanks so much @Madraceee, let me know if I can help

[Madraceee]

I will go through the repo and start working asap!!

[Madraceee]

@dfarr If my understanding is right , I have to make a new command which calls the callback functions from "pkg/client/v1/v1.go" ?

[dfarr]

Yes that's correct! The parameters to that call correspond to the flags the command should expose, as detailed above, the only tricky parameter is recv which can be either a string or an object as detailed above.

[Madraceee]

Got it
I will work on this

[Madraceee]

I have two doubts

1. What should be the contentType when sending default or a url?

[Madraceee]

Other than the contentType part,
I have written the code. I am still learning the whole functionality, so can you look at my code and let me know if any changes has to be done?
I can push the changes if you are okay with it.
