deploy: work with fewer arguments

Context

As a user of KDT, whenever I want to run a deploy I have to pass as command line args: the build, context, artifact, etc., am I forgetting something?Basically, there are too many flags I need to pass to make a deploy, and most of the time I am using the same flags for a specific deploy (i.e. normal deploy to prod always uses the same 4/5 flags, why do I have to specify them every time).What I would like is some way to specify my default flags for a deployment (ex. in some yaml) so that I can say something like

kdt deploy production

and that would be the equivalent of passing all the flags I normally use to specify a production deploy.

Request

I should still be able to pass command line flags together with this new system, and command line flags would override the defaults.

Acceptance Criteria

enable new/current users to use kdt without having to discover somehow what all the required flags are.

Hints

• interactive mode? That asks for required flags?
• Add docs that tell you exactly what you need to run commands?
• man-page like docs for kdt. At least for kdt deploy
