Did you change the file? If so, how?

No

Describe the issue

The GRPC metrics no longer show up with the latest version of spanner library. After testing, it was found that we need to change the dependencies for the metrics to work.

@rajatbhatta Would you mind taking a look at this?

As per internal documentation, most likely the cause of the issue is misconfiguration on the customer's end like not including critical dependency like grpc-census in their application. We don't have to modify any dependencies from the client libraries side. Thanks! Closing.
