CSIT jobs should use a set of streams, not a list of branches

As an AAI developer, i need to remove the references to the branches in favor of using streams, as per this example:

—

• project:
  name: integration-docker
  project-name: 'integration'
  jobs:
• ' {project-name}-{stream}-{subproject}-docker-merge'
  - '{project-name}

  -

  {stream}

  -

  {subproject}

  -docker-verify'
  project: 'integration'
  stream:

• 'master':
  branch: 'master'
• 'amsterdam':
  branch: 'amsterdam'
  subproject:
• 'sniroemulator':
  pom: 'test/mocks/sniroemulator/pom.xml'
  pattern: 'test/mocks/sniroemulator/**'
  mvn-settings: 'integration-settings'
  files: '**'
  archive-artifacts: ''
  build-node: ubuntu1604-basebuild-4c-4g
