replace yargs with bossy about confidence

[lloydbenson]

This may require some enhancement to bossy as well. I think it needs some additional love to handle the --filter object type logic. I have pinged @geek on that.

thanks lloyd :D

@devinivy if there's no plan to add object type logic in bossy in the near future, should we close this issue? It's been open for a while now

[devinivy]

@augnin Yeah, all good by me! We can always reopen in the future if there's movement from the bossy side.
