The existing URL no longer works. This commit updates the Chart
dependencies to use the new Stable chart URL.
This will fix the "Chart not found" errors that occur if these example
resources are used.
Please keep in mind this is only a bandaid, as the repository is still
EOL, and should not be used.
* Adding one more example - keycloak - alongside with dex IDP.
* don't expose keycloak and proxy ports to the host
* specify email-domain list option in documentation
* get rid of nginx and socat to simplify the example as per https://github.com/oauth2-proxy/oauth2-proxy/pull/604#issuecomment-640054390
* get rid of the scripts - use static file for keycloak startup
* changelog entry
* Update CHANGELOG.md
