Dockerfile: add OpenSSL to Docker container
Add OpenSSL to the dex Docker container so wget can be used to query HTTPS endpoint. This is a requirement for health checking when dex is doing its own TLS termination. This increased the image size from 20.37 MB to 20.92 MB (+550 KB). Additionally add Ed and Rithu as maintainers.
