Documentation on how to add pipeline processor

[OElesin]

This is an excellent project. However, only supports KubeFlow pipelines as processor. Can you please provide some documentation on how to add more pipeline processor?

I would love to see if this can work with AWS Step Functions Data Science SDK.

Thanks in advance!

@OElesin There are some initial pipeline documentation in our repo, but the overall flow is Pipeline Editor -> Scheduler Handler -> Parsing -> Processor. The processor is pluggable and there is one per runtime. We currently have the (Kubeflow Pipeline processor)[https://github.com/elyra-ai/elyra/blob/master/elyra/pipeline/processor_kfp.py] and an in-progress Airflow Pipeline processor by @akchinSTC
