Description of PR

This is the feature branch feature/HADOOP-18028-s3a-prefetch rebased on trunk to see how yetus likes it.

If all is good I will force push it to the asf branch, so things are up to date.

rebase merge issues

  • Constants, docs
  • S3AReadOpsContext

some compilation errors to fix

How was this patch tested?

For code changes:

  • Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
  • Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
  • If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
  • If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
