Publish robot

[justinlittman]

Then goal of this ticket is to run the publish robot within DSA. This will simplify the current flow:

1. Workflow Server Rails submits a publish job to the Robot Sidekiq.
2. Robot worker receives the publish job from Robot Sidekiq.
3. Robot worker invokes DSA publish endpoint.
4. DSA publish endpoint submits a publish job to DSA Sidekiq.
5. DSA worker receives the publish job from DSA Sidekiq.
6. DSA worker performs publish.
7. DSA worker invokes Workflow Server Rails update workflow step endpoint.

to:

1. Workflow Server Rails submits a publish job to the Robot Sidekiq.
2. DSA Robot worker receives the publish job from Robot Sidekiq.
3. DSA Robot worker performs publish.
4. DSA Robot worker invokes Workflow Server Rails update workflow step endpoint.

This same approach can be applied to other workflow steps; this is just the first.
