I have some compiling issues on the entire workspace. Thus I only run checks for opentelemetry-proto:

~/repo/opentelemetry-rust on bump-tonic-prost !1 
❯ cargo check -p opentelemetry-proto            
    Finished dev [unoptimized + debuginfo] target(s) in 0.07s

~/repo/opentelemetry-rust on bump-tonic-prost !1 
❯ cargo clippy -p opentelemetry-proto           
    Finished dev [unoptimized + debuginfo] target(s) in 0.07s

Maybe there are other errors can't be reported

Well, I guess my compile error is caused by tikv/grpc-rs#618. But when I tried to bump grpcio to 0.13 I found it still dependents on prost 0.11....
