Ignore HEAD requests in ShallowEtagHeaderFilter
Prior to this commit, the `ShallowEtagHeaderFilter` could participate in the response and set its ETag/Content-Length headers, even for HEAD requests. Since the response body is empty, the filter implementation would set a `"Content-Length: 0"`. The RFC states that responses to HEAD requests should exhibit identical response headers to GET (with the possible exception of payload related headers such as Content-Length. With this commit, `ShallowEtagHeaderFilter` now ignores HEAD requests since the proper values may be set already for payload related headers by the handler. The filter has no way to generate a proper ETag value nor calculate the content length without the actual body. Issue: SPR-15261
