Agent check gRPC version against server (#1653)
close #1114

As long as the `VersionResponse` type is not changed the check will
fail/pass gracefully

example output:
```
{"level":"error","error":"GRPC version mismatch","time":"2023-03-19T19:49:09+01:00","message":"Server version next-6923e7ab does report grpc version 2 but we only understand 1"}
GRPC version mismatch
```
