[Feature Request] Scrub span tags

[tealwp]

Adding an option to the instrumentation setup for databases to scrub any span attributes the user doesn't want sent with the trace. For example, we use custom built spans, alongside instrumented span events through postgres. Being able to remove the db statement tag from the span would be helpful, as the db statements can include personal information.

Would something like redact solve your issue?

Ideally we'd be able to use the TracerProvider that distro.Run() sets up. Looks like to use redact we'd have to set up a NewTracerProvider. We may end up adding filters to the Collector, but I think there may be some benefit to adding config options to the initial instrumentation.
