Benchmark

Since GDAL 2.3, HTTP2 is available is compiled against libcurl+nghttp2. AS GDAL docs says, enabling HTTP2 can be positive when working with Cloud Optimized GeoTIFFs to save some range requests.

The interest of enabling HTTP/2 is the use of HTTP/2 multiplexing when reading GeoTIFFs stored on /vsicurl/ and related virtual file systems
