Review WorkflowManager WorkflowRequestEvent logic

[JoeBatt1989]

The WorkflowRequestEvent logic seems dependent on the size of the study sent. This ticket is to review the logic around consuming WorkflowRequestEvent and seeing if there are any potential performance improvements. Details of what was seen during the performance test can be seen below. CT (324 slices) is by far the longest processing time, which conditional logic oly making 1-2 seconds difference, which is expected.

Modality	DICOM Payload Processed	Task Dispatched (WorkflowRequestEvent cosumption)
Average (sec)	Max (sec)	Average (sec)
CT1 ("{{ context.dicom.series.all('0008','0060') }} == 'CT'")	34.4	36.2
CT1 ("{{ context.dicom.series.any('0008','0060') }} == 'CT'")	34.2	37.8
MR	1.1	1.4
US	1.7	2.3
RF	0.7	1.2
CT (executing Small app or conditional logic)	34.9	37.9
RF (no conditional logic)	0.7	0.9

If performance is related to the number of (DICOM JSON) files, then we may consider improving it with Project-MONAI/monai-deploy-informatics-gateway#83.
