Nick Dimiduk 489af42792 HBASE-26545 Implement tracing of scan ... * on `AsyncTable`, both `scan` and `scanAll` methods should result in `SCAN` table operations. * the span of the `SCAN` table operation should have children representing all the RPC calls involved in servicing the scan. * when a user provides custom implementation of `AdvancedScanResultConsumer`, any spans emitted from the callback methods should also be tied to the span that represents the `SCAN` table operation. This is easily done because these callbacks are executed on the RPC thread. * when a user provides a custom implementation of `ScanResultConsumer`, any spans emitted from the callback methods should be also be tied to the span that represents the `SCAN` table operation. This accomplished by carefully passing the span instance around after it is created.
