Fail fast on dependencies env option

[justinorringer]

Adding a fail fast variable. In ephemeral, if we set it to false it should help those dependency issues.

Defaulting the value to true in the clowdapp, so we shouldn't have to add the value to app-interface for stage and prod.

I was able to deploy this and verify that vulnerability engine, as an optional-dep, was not deployed and VA was able to successfully run.

Bonfire config..

 (iqe-astro-va-plugin) jarice:~>cat .config/bonfire/config.yaml
---

apps:
- name: virtual-assistant
  components:
    - name: virtual-assistant
      host: local
      repo: ~/git/justin_astro_va
      path: /deploy/clowdapp.yaml
      parameters:
        IMAGE_TAG: pr-458-latest

Ran iqe deployment with...

iqe tools test -t test_VA_dialogue --ref-env insights-stage -UD astro_va --deploy_args "--no-release-on-fail --no-remove-resources virtual-assistant --timeout=3000 --optional-deps-method none"

And this in deploy/clowdapp.yaml...

    dependencies:
      - advisor-backend
      - notifications-gw
      - notifications-backend
      - content-sources-backend
      - sources-api
      - rhsm-api-proxy
      - ccx-smart-proxy
      - chrome-service
      - rbac
    optionalDependencies:
      - vulnerability-engine
