Description

The connector source includes 3 `.proto` files that define the Prometheus Remote-Write wire protocol, also including GoGoProto the Prometheus `proto` depends on.

• `proto/remote.proto`
• `proto/types.proto`
• `proto/gogoproto/gogo.proto`

These schema definitions are redundant, because the connector includes the Protobuf-generated Java classes, and should be removed
