No Start State

[Leahh02]

This should allow the user to cancel a workflow submitted with the no-start state. The correct state should also come up when they query the workflow. The correct state should also appear in the graph database.

I should probably standardize the capitalization. For example, when I query the workflow I get

No Start
cat--No Start
grep0--No Start
grep1--No Start
tar--No Start

and when I start and then query I get

Running
cat--COMPLETING
grep0--WAITING
grep1--WAITING
tar--WAITING

So I need to make it NO START

I would think the Workflow state would be Not Started and the tasks could be blank.
Waiting for Submit for the Workflow

I would think the Workflow state would be Not Started and the tasks could be blank. Waiting for Submit for the Workflow

I can do that instead!

After commit 8ba84cf the output looked like:

No Start
cat--
grep0--
grep1--
tar--

Then in commit 9841e8f I decided to remove the -- so now it looks like:

No Start
cat
grep0
grep1
tar

@Leahh02 This looks good to me and works well. You will need to fix the conflicts. I've asked @kabir-vats to review it, if he has time.

Nice addition to allow a user to specify a workflow and verify the tasks and a first step in verifying the workflow dependencies.
