C386/launch

[BSick7]

This PR adds the launch CLI command that performs push, deploy, and log (tailing logs).

While making a nice experience, the following changes were made:

• Reusing CLI flags across CLI commands
• Fixed usage text to notate [options] correctly (as a result of previous CLI upgrade)
• Reuse of common CLI setup for push, deploy, log, launch into single AppAction
  • Setting up profile
  • Finding information about application, environment, and workspace
  • Discovering app provider
• Indenting output of infrastructure configuration
