Create an API endpoint to provide status on application build status per Git repository

Create an endpoint, possibly a AWS lambda, to provide build status information back to the user.

i was thinking about this as i was creating a high level test case for application-package builds (apgs):

  Scenario Outline: Successful Application Package Builds
    Given I have a token to authenticate with Unity Services
    When I submit <repo_name> to the apgs build system
    Then the apgs build response is <result>
    And I wait for the apgs build to complete
    And the completed apgs build information references <repository>
    And the completed apgs build information references the application catalog

my initial thought is:

1. the request to the apgs should return a response almost immediately (e.g. success| failure and a job ID)
2. Job_id can be queried for status (accepted, in progress, success, failed) (thoughts?)
3. once the job is completed, a 'result' should be available, the result should contain:

• Warnings/Errors (?)
• the location of the artifact (e.g. built and published to dockerhub)
• The location of the application pacakge files (e.g. dockstore)

See if this can just be a way of proxying the Pipelines API
