------------------------------------

             Summary: allow aurora executor to be customized via the commandline
                 Key: AURORA-216
                 URL: https://issues.apache.org/jira/browse/AURORA-216
             Project: Aurora
          Issue Type: Story
          Components: Executor
            Reporter: brian wickman
            Priority: Minor


Right now the AuroraExecutor takes runner_provider, sandbox_provider and status_providers.  These need to be the following:
  - runner_provider: TaskRunnerProvider (assigned_task -> TaskRunner)
  - status_providers: list(StatusCheckerProvider) (assigned_task -> StatusChecker)
  - sandbox_provider: SandboxProvider (assigned_task -> SandboxInterface)

These are generic enough that we should allow these to be specified on the command line as entry points, for example, something like:

{noformat}
  --runner_provider apache.aurora.executor.thermos_runner:ThermosTaskRunnerProvider
  --status_provider apache.aurora.executor.common.health_checker:HealthCheckerProvider
  --status_provider myorg.zookeeper:ZkAnnouncerProvider
  --sandbox_provider myorg.docker:DockerSandboxProvider
{noformat}

Then have these loaded up using pkg_resources.EntryPoint.  These plugins can either be linked into the .pex or injected onto the PYTHONPATH of the executor.
