Streamline CLI commands to reduce the duplicate initializations

[jrschumacher]

Not critical right now. What I'd like to do in the next refactor is move NewHandler and InitProfile into the cli.New() process... I feel like we can handle the close as part of c.Close() and make sure it's uniform.

I think part of that work will be adding cli.New() to the preRun process. Not sure if we can pass the object back to the command, but something to look at later.
