Created d-Flow angular app

[esune]

The PR contains the initial review for the re-implementation of the Permitify demo app in Angular.

Other than being an Angular app, the main change is the new graph UI, which is updated dynamically as the user proceeds through the steps in the demo.

Currently the topology definition is served from a hard-coded JSON file, work to wire up the API call and make the whole system more flexible is currently in progress.

@nrempel please wait to merge if the code looks okay, I will update this PR to allow OpenShift to build and deploy correctly

[nrempel]

The graph looks great!

The code looks good to me. I like the directory structure approach you took for components 👍🏼

When I click on a credential from the graph it looks like a get an error from the org book:

Besides that error, looks good to me!

Not necessary immediately, but what do you think about migrating the rest of the application to the angular app? Just something to think about

[esune]

@nrempel : I don't seem to be able to reproduce the issue, I tried registering a couple of corps. and generating proofs and I can always see them in ToB:

About moving everything to the angular app: it will not be possible to move the resources required by the agents into the angular app, as they need to be served/injected into each agent using the proxy.
I will, however, try to clean up the directory structure once I have it all finalized and working smoothly.

Discussed changes in person, as per above comments.
