Support for DD_TRACE_DB_CLIENT_SPLIT_BY_INSTANCE

Are you requesting automatic instrumentation for a framework or library? Please describe. No

Is your feature request related to a problem? Please describe. The service name of spans for db operations is not clear enough. For examples, the service name of spans for mysql query is MyService-mysql, which does not show the database name. And if I have multiple services that query same database, then service names are MyService1-mysql, MyService2-mysql etc.

Describe the solution you’d like The service name of spans for db operations should be database names, like what we have done in dd-trace-java.

Describe alternatives you’ve considered As an alternative, we can use database host name or ip address as service name of spans.

Thanks, we’re aware this is a limitation at the moment, and we’re planning a long term solution to the problem of service naming across Datadog. We’ll be sure to let you know when we have solid plans.

Has there been any progress on the long term solution to this problem? We are a subscriber with a number of services that connect to multiple databases and the functionality described in this pull request would be very beneficial to us.
