### What would you like to happen? Google Spanner Emulator currently only supports the execution of one transaction at a time ([link to source](https://github.com/GoogleCloudPlatform/cloud-spanner-emulator/blob/53eaa404d303fb2dc03f3b444553aa9bb24c3786/common/errors.cc#L453-L455)). That makes it really challenging to do any testing of Dataflow jobs using spanner writes. `SpannerIO` already retries aborted transactions if they happened during the schema change, just by looking at the abort error message ([here](https://github.com/apache/beam/blob/a46a35b52fc145649312ebfa4801d0784dd807ae/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/spanner/SpannerIO.java#L2123-L2151)), which seems like a suitable place to also check if message comes from Emulator complaining about concurrent transactions ### Issue Priority Priority: 2 (default / most feature requests should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [X] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
