Default bind to higher port in www component

[wkoot]

• [ ] Change the default PROXY_PORT to 8080, so we don't bind a privileged port. Since this will remove backwards compatability and changes to docker-compose, it requires a major release.
• [ ] Remove CAP_NET_BIND_SERVICE from the proxy Dockerfile and helm deployment. This will allow for easier deployments on environments that have stricter rules.
• [ ] Update deployment documentation
• [ ] Update software documentation
• [ ] Update versioning policy
