Patch 004
* fixed name of fs.s3a.block.output option in core-default and docs. Thanks
Rajesh!
* more attempts at managing close() operation rigorously. No evidence this is
the cause of the problem rajesh saw though.
* rearranged layout of code in S3ADatablocks so associated classes are
adjacent;
* retry on multipart commit adding sleep statements between retries
* gauges of active block uploads wired up.
* more debug statements
* new Progress log for logging progress @ debug level in s3a. Why? Because
logging events every 8KB gets too chatty when debugging many-MB uploads.
test: s3a ireland

> An AWS SDK [issue|https://github.com/aws/aws-sdk-java/issues/367] highlights
> that metadata isn't copied on large copies.
> 1. Add a test to do that large copy/rname and verify that the copy really
> works
> 2. Verify that metadata makes it over.
> Verifying large file rename is important on its own, as it is needed for very
> large commit operations for committers using rename
