Processing Jobs tagging and multiple nodes running on the same instance.

[DarkJoker9817]

Hello and thanks for this plugin. I have three questions:

1. I want to assign a tag (in addition to those assigned automatically like 'sagemaker:pipeline-execution-arn' and 'sagemaker:pipeline-step-name') to the Processing Jobs launched through this plugin. Is there a way to do this automatically without interfacing through the AWS management console?
2. I want that all the nodes runs on the same instance. The default behaviour is that when a step of the pipeline is executed a new instance is start-up and when it finishes the instance is shut-down increasing the total execution time. Is there a way to make it executing on the same instance to optimize execution time?
3. Moreover I have some nodes that can be executed in parallel, can I do this configuring the plugin in a certain way?
