code: public S buildProxy(RetryPolicy retryPolicy) {
          return ServicePoolProxy.create(_serviceType, retryPolicy, build(), _partitionContextSupplier, true);
      }
docs: Builds a dynamic proxy that wraps a {@code ServicePool} and implements the service interface directly.  This is
  appropriate for stateless services where it's sensible for the same retry policy to apply to every method.
  <p/>
  It is the caller's responsibility to shutdown the service pool when they're done with it by casting the proxy
  to {@link java.io.Closeable} and calling the {@link java.io.Closeable#close()} method.
  
  @param retryPolicy The retry policy to apply for every service call.
  @return The dynamic proxy instance that implements the service interface {@code S} and the
  {@link java.io.Closeable} interface.
