HADOOP-13309: Document S3A known limitations in file ownership and pe…
…rmission model.
Summary:
* Update file system specification to describe that object stores may have
a different authorization model than HDFS and traditional file systems.
* Update hadoop-aws documentation to warn that S3A will return stub
information for metadata related to ownership and permissions. I wrote this
information from the assumption that the HADOOP-12774 change gets finished, so
that one will have to get committed first.
* Also update a few cosmetic things near the part of the hadoop-aws
document that I changed.

> Components: fs/s3
> Reporter: Chris Nauroth
> Assignee: Chris Nauroth
> Priority: Minor

> S3A does not match the implementation of HDFS in its handling of file
> ownership and permissions. Fundamental S3 limitations prevent it. This is a
> frequent source of confusion for end users. This issue proposes to document
> these known limitations.
