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.
