Implementations can be automatically discovered by gRPC via Java's SPI mechanism. For
automatic discovery, the implementation must have a zero-argument constructor and include
a resource named
META-INF/services/io.grpc.NameResolverProvider in their JAR. The
file's contents should be the implementation's class name. Implementations that need arguments in
their constructor can be manually registered by
Implementations should not throw. If they do, it may interrupt class loading. If
exceptions may reasonably occur for implementation-specific reasons, implementations should
generally handle the exception gracefully and return
