Review Comment:
`value: {@value}` wouldn't render with toLowerCase(), added for other
statements.

> 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.
