`oasis deploy` with additional arguments

It would be great if we could deploy with arguments from the cli. Or there should be docs to explain how the user should go to scripts/deploy_service.js to add the arguments themselves.

It's unclear how to parse complicated structs as CLI arguments. I like having deploy scripts since it's repeatable and explicit, but maybe we could consider a node module or python package or something that allows deploying in a REPL environment.
