feat(service): upgrade the ego-server inside the feat.ego_server_run branch to enable attested tls.

[qascade]

Description

Ego gives an example for the server to verify that the payload is coming from a trusted source. I want to enable that feature inside the clean room server, which runs inside the sgx enclave. Please note as we are just simulating the tee, you can assume the server to be Root CA itself.

How are you planning to resolve on this issue?
