Boost S3A Stream Read Performance

    Description

      calibrate S3A input stream performance against recent applications/data formats and improve where necessary.

      HADOOP-18028 is a key part of this, but there are other issues/opertunities

      1. we could add machine parsable trace-level logging in FSDataInputStream to collect stats on how stream apis are invoked, so collect data from real apps; analyze
      2. implement those APIs which some apps use (ByteBufferPositionedReadable), not so much for direct implementation as to get better information from the app as its read plan
      3. the `normal` mode doesn't switch from sequential on forward seeks. Is that always appropriate?
      4. choose different buffering options when doing whole file IO vs sequential vs random
