Output formats

[andyjeffries]

I think we should implement a global -o=json or --output=json which outputs in JSON format for neat scripting in to jq.

I also think we should consider a -q which gives a quieter output to commands. For example:

$ civo instance password gitops-prod -q
foo-password-here
$ civo instance password gitops-prod
The password for gitops-prod.example.civo.com is foo-password-here # with green highlights

-q implemented for instance public_ip and instance password` so far. civo/cli@982ba49
