To create a CLI for spinup backend.

[viggy28]

At least the CLI should be able to provide version info, list clusters, stop and start clusters.

@idoqo already created start. I guess it's a matter of time to support other commands.

@viggy28 I like to work on on of the commands. I will start with the version info command

[idoqo]

Great @tharun208, go for it - quick one: what do you propose we show in the info command?
