TODO: This was copied with few adaptations from here: https://github.com/confidential-containers/guest-components/tree/main/api-server-rest This needs to be tested and verified if the instructions still work and needs a rework.CoCo guest components use lightweight ttRPC for internal communication to reduce the memory footprint and dependency. But many internal services also needed by containers like get_resource, get_evidence and get_token, we export these services with restful API, now CoCo containers can easy access these API with http client. Here are some examples, for detail info, please refer rest API
