Review Comment:
Thanks for the suggestion. It's a good idea to have the header values
trimmed and headers without any values should be skipped. So I have updated the
logic and unit tests accordingly.
> S3A: support custom S3 and STS headers
> --------------------------------------
>
> Key: HADOOP-18562
> URL: https://issues.apache.org/jira/browse/HADOOP-18562
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Daniel Carl Jones
> Assignee: Prerak Pradhan
> Priority: Minor
> Labels: pull-request-available
>
> Some users have the use case where for a particular S3A filesystem, they
> would like to set one or more headers to a static value.
> We might imagine a set of configurations properties with a common prefix,
> where the suffix determines the header name and the value of the property
> determines the value of the header.
> Per-filesystem headers can be set using the per-bucket configuration.
