Test Plan

Reset your local DB
Navigate to this url

First, trying changing the name of a stage and submitting the change.
That should work fine.

Next try removing or adding a move constraint to something:
For instance remove ask for permission from submitted.
You should note ask for submitted gets moved into its own workflow bc it has been disconnected from submitted. It is now its own workflow.

Try reconnecting or removing move constraints and changing the name. Note any unexpected behavior.

Notes/Context/Gotchas

@eric has mentioned in meetings recently about the notion of viewing how things move through stages as a DAG.

For Instance, Lets say we have nodes A, B, C, D, E:
A-> B, D, E
B-> C, E
C-> D, E

We can build a simple dag

stateDiagram-v2
   [*] --> A
   A --> B
   A --> D
   A --> E
   B --> C
   B --> E
   C --> D
   D --> E
   E --> [*]

Where the end is some output(our pub filled snowball)

How do we thus visualize a list of stages if some are not connected to any other? How do we visualize workflows that use these nodes when they are a subgraph of our DAG.

For instance, if we add A(1) and A(1) has nothing connecting it to A

stateDiagram-v2
   [*] --> A
   [*] --> A(1)
   A(1) --> D
   A --> B
   A --> D
   A --> E
   B --> C
   B --> E
   C --> D
   D --> E
   E --> [*]

How do we show one list of of stages
-- (A->B->C-D->E)
and another
-- (A(1)->D->E)

This has not been solved yet, but is very important to keep in mind when testing this PR. If you remove all constraints to and from a stage, it forms its own subgraph, and essentially becomes a root
