CLI format flag over 'pretty' option

[asonnenschein]

Problem The CLI does not currently support pretty printing JSON outputs from commands. This is annoying because JSON can be difficult to read when it's not pretty printed, and users will need to pipe CLI outputs to custom bash commands to pretty print their JSON. Supporting pretty print as an optional argument in the CLI will be a better UX.

Solution Enhance the CLI with an optional argument to pretty print JSON outputs to stdout.

A/C

• CLI supports a new optional argument to pretty print JSON outputs to stdout for all APIs.
