The gRPC client is unable to resolve DNS address of the server unless the
GRPC_DNS_RESOLVER environment variable to "native". I expected gRPC to work
out of the box and c-ares would be able to resolve the servers DNS address.
Below are the logs:

### What version of gRPC and what language are you using?
C# .Net Standard 2.0
gRPC 1.21.0
Any help is greatly appreciated!
