Currently, the beacon node has no ability to serve the HTTP API over TLS. Adding this functionality would be helpful for certain use cases, such as when you need a validator client to connect to a backup beacon node which is outside your local network, and the use of an SSH tunnel or reverse proxy would be inappropriate. ## Proposed Changes - Add three new CLI flags to the beacon node - `--http-enable-tls`: enables TLS - `--http-tls-cert`: to specify the path to the certificate file - `--http-tls-key`: to specify the path to the key file - Update the HTTP API to optionally use `warp`'s [`TlsServer`](https://docs.rs/warp/0.3.1/warp/struct.TlsServer.html) depending on the presence of the `--http-enable-tls` flag - Update tests and docs - Use a custom branch for `warp` to ensure proper error handling ## Additional Info Serving the API over TLS should currently be considered experimental. The reason for this is that it uses code from an [unmerged PR](https://github.com/seanmonstar/warp/pull/717). This commit provides the `try_bind_with_graceful_shutdown` method to `warp`, which is helpful for controlling error flow when the TLS configuration is invalid (cert/key files don't exist, incorrect permissions, etc). I've implemented the same code in my [branch here](https://github.com/macladson/warp/tree/tls). Once the code has been reviewed and merged upstream into `warp`, we can remove the dependency on my branch and the feature can be considered more stable. Currently, the private key file must not be password-protected in order to be read into Lighthouse.
