HTTP/2 question
Is there a way to configure the client to _not_ include a Host header in
HTTP/2 requests? Currently, my client is sending a Host header in addition
to the relevant HTTP/2 pseudo-headers (i.e. :scheme and :authority), and it
seems to be screwing up AWS request signing.

Hi Ryan
Generally HttpClient does not meddle with headers added manually by the
caller, with exception of `Content-Length` and `Transfer-Encoding`
values.
I imagine there are legitimate cases when one may want to manually set
`Host` header, for instance when working with virtual hosts.

It turned out that there was code elsewhere that was manually adding a Host
header, which the client was including like any other request header.

Hi Ryan
The standard request interceptor never generates a `Host` header for
HTTP/2 request messages
https://github.com/apache/httpcomponents-core/blob/master/httpcore5-h2/src/main/java/org/apache/hc/core5/http2/protocol/H2RequestTargetHost.java#L57
Can there be a custom request interceptor in the request execution pipeline causing the issue?
cheers
