Enhance the v3 APi for workflows

[TheCoffeeDude]

Enhance the v3 APi for workflows - /v3/workflows/{workflowid} - to get information for first n versions and/or last n versions of the workflow.

The problem

The current API will return information about all versions of a workflow. If a workflow has several hundred versions, you'll get all version information, much of which is useless and can take a long time to process.

The (potential) solution

Allow the API to take parameters like first n versions and last n versions. This will allow the API to return only the respective version information that would be of interest to the user.

The red box in the image is the enhancement in swagger:
