Dump subcommands information into json for consumption by other commands

[mks-m]

golang binary could use this for printing help messages or generating autocompletion, etc

This is interesting... does it work?

I don't consider this a "public" command, can you move it out of the main paasta part and into something like paasta_dump_command_choices or something? That way it isn't in the "critical" path of the main paasta command, doesn't slow it down, etc.

[mks-m]

it does work, i don't know if we really need it, maybe eventually, i'll just let it sit here for now

[solarkennedy]

@keymone Are you still planning on taking this approach?

[mks-m]

yes, eventually, it's a bit low on priorities list.
