[Feature Request]: Transaction and Request Tags on SDK connecting to Spanner

[iyertalks]

What would you like to happen?

Spanner provides a set of built-in statistics tables to help you gain insight into your queries, reads, and transactions. To correlate statistics with your application code and to improve troubleshooting, you can add a tag (a free-form string) to Spanner read, query, and transaction operations in your application code. These tags are populated in statistics tables helping you to correlate and search based on tags.
