Seems good.

Review Comment:
ok. I'm going to propose here doing all the next lines
in a single <pre> as there's enough formatting it wouldn't render right.
you can then cut the {@literal} bits.
The goal here is generally "looks good on an IDE rendered view"

> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Daniel Carl Jones
> 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.
