IMPALA-10504: Add tracing for remote block reads
This patch logs metadata for the first unexpected remote read of each
scanrange. This logging is intended to help diagnose the root cause of
remote reads. Since a message may be logged for each scan range,
there could be several hundred lines of output in a degenerate case.
However, the remote read condition is not expected and verbose
output may be needed to diagnose the root cause.
