Create Stepper Component Eventing

[wwitzel3]

I marked this as blocked by #1102 if folks want to start on this before #1102 is ready, you'll want to work closely with the person working on #1102 (consider pairing?).

A well defined step of steps, the inputs for a given step may change based on input from the previous step. For now, we will not be dynamically adding steps.

What we know

State delivered from server.
The Headings of a stepper should be well defined. We know the steps.
The contents of each step may change based on input.
We will want to be able to assign an action handler to the final step.
Fields of the stepper will be delivered via action Payload

Two approaches:

Fat component:

• Contains all of the possible out comes for the options of the stepper.
• The config struct from the server could get very large.
• Depending on the information is may take a while to build on the options from various API/resource calls.
• All validation is populated in the config as well.

Dynamic component:

• Step contents change based on input.
• More complex client code.
• Handling the failure of async calls to load data.
