Create lambda for running RNASums

[alexiswl]

Something for the new 'button' to trigger.

Given a subject id, and a dataset, generate a ready event for RNASum using the latest version of UMCCRise and WTS for a given subject

Update: Given a portal run id (of an existing RNASum event), and a dataset id, find the READY event from the workflow manager and then perform a find-replace on all existing versions of that old portal run id with a new portal run id.
For the new WorkflowRunStateChange READY event, remove the payload.refId attribute and refresh the 'timestamp' attribute with the current UTC time
