[epic] Document CLI

[adegeo]

Describe the issue or suggestion

• Scenarios to cover in docs

  • Acquisition
  • New projects (templates list)
  • Adding integration packages
  • Running
  • Publishing
  • CLI -> AppHost integration

• CLI Reference

• Cover install script in the acquisition doc

• Install script reference

• Document the CLI reference, though this is lower priority than the scenarios since the CLI itself has help built in.
