Docs and helm fix

[halkeye]

A couple of super minor things.

Docs:

• I got bit by scope: "" in the docs for oidc, and had to dig in code/error messages to realize issuer was the url, and redirect url could be anything

Helm charts:

• Service - I use external-dns annotations to let my loadbalancer ips define a hostname, so added support for annotations
• Service - Added support for service externalTrafficPolicy - service.spec.externalTrafficPolicy - denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints. There are two available options: Cluster (default) and Local. Cluster obscures the client source IP and may cause a second hop to another node, but should have good overall load-spreading. Local preserves the client source IP and avoids a second hop for LoadBalancer and NodePort type services, but risks potentially imbalanced traffic spreading.
• Ingress needs to point at the container port (8000) not the service port (80)
• Made the config map changes restart the deployment (checksum annotation suggested by helm)
• Made the configmap have the entire config section. I'm pretty sure i didn't break anything since only including wireguard is one level too deep and keys won't match up.

Thanks so much for the changes here. I'll try to get this merged over the weekend and added to the 0.2.0-rc release.
