Endpoint to trigger a workflow

[reskyner]

Add a view to trigger a workflow.

Info needed:

• zipped input(?) or json object containing required data
• workflow name
• workflow type

With that info, we should be able to send the data to a specific workflow (wherever that is) to be executed

Workflow code should be written and maintained in a separate repository (e.g. a collection of nextflow, galaxy, squonk etc. workflows) that contains all of the code needed to execute the workflow in/on the correct container/serrvice - the endpoint should return:

1. A success/fail notification for if the workflow has started
2. An id for the workflow/task

The ID should then be able to be used at an additional endpoint to examine the status
When the workflow is complete, a final endpoint will be used to import/download the data
