Production build with Node and Docker

[oscar60310]

What’s the problem you're trying to solve

We need a production build that only includes necessary context, e.g. artifacts, production dependency, serve package ...etc.

Describe the solution you’d like

Provide package command to do production builds, and use --output flag to indicate the output type. We can implement node and docker output first:

• Node:
  Build: vulcan package --output node
  Execute: node ./dist/index.js
• Docker
  Build: vulcan package --output node && docker build ./dist
  Execute docker run <image

Additional context

• We should prepare the resources e.g. dockerfile and all the contents then print the "docker build" commands to users instead of calling docker API directly. Because we might not able to call docker API from Vulcan CLI, e.g. using CLI in docker Package CLI tools with Docker #49
