Migrate telemetry ingestion service

[tltran-legion]

Summary

Goal is to migrate the Telemetry service to OpenAPI using the Code Generation framework.

Current State

At the moment, the Telemetry service is using gRPC we need it to follow the defined new API convention.

Work Items

• Using the Code Generation Framework to generate the service skeleton.
• Port of the actual business logic of the service into the new skeleton.

[mad-legion]

The telemetry ingestion service already supports http and grpc.
Most the work will be to move the rust telemetry client to use http (the unreal client is already using http).
Not sure OpenAPI will do much good here as part of the protocol is binary.
