Triggering authenticated workflows

[DiamondJoseph]

See also

There should be a simple way of causing workflows to be run in Argo when a plan is created.
The workflow should be able to run per-plan or per-run, or be a persistent workflow when required to be long running (e.g. Neural Net while training?)
The workflow should inherit the authetnication information of who triggered the run

Acceptance Criteria

• There is a decorator that causes workflows to be run up in the argo workflow system to enable adaptive plans/post processing etc.
