How I use OpenFaaS as an end-user

[kylos101]

Finally contributing to #1591. My apologies for the delay! I decided to put together diagrams showing how I use OpenFaaS.

Let me know if this is something you'd be interested in, have questions, or would like any changes?

Description

Architecture diagrams for:

1. Integrating Auth0 with OpenFaaS to enrich claims in JWT tokens via a HMAC event based rule at login
2. My Angular SPA using OpenFaaS to do a variety of things
3. My Kubernetes backend for OpenFaaS, ingress managed using Kong plugins
4. A flow diagram for my OpenFaaS functions
5. A diagram highlighting various administrative processes and related components
