Deploy compositions as part of aio app deploy

[aligent-lturner]

Currently, there is no way to deploy a composition using the aio cli. Instead, we need to manually install the openwhisk-composer package, set up environment variables (or a .wskprops file) and deploy manually.

What I'd like to happen is to be able to reference a composition's JS file in the manifest, and have it deployed with the rest of the application.

• Define the composition in a JS file somewhere (e.g. a compositions folder)
• Declare the composition in app.config.yaml - suggested format:

runtimeManifest:
  packages:
    myPackage:
      actions:
       ...
      sequences:
       ...
      compositions:
        compositionA:
          definition: src/compositions/compositionA.js
          web: 'yes'
          annotations: 
            require-adobe-auth: true

Being able to deploy all actions, sequences and compositions via a single command would be highly preferable, compared to the current situation, where a composition has to be deployed separately (and then updated to be web-accessible, etc. if desired)
