I'd like the cattle agent to be able to communicate in plaintext to enable Egress TLS Origination through Envoy in complex IT environments (e.g., MITM, certificates, proxies). I noticed that 'wss' and 'https' are hardcoded in the agent's code, which limits flexibility. I think we could add an extra environment variable like CATTLE_INSECURE_CONNECTION for this use case. Do you think it would be possible to open a PR for this?
