Contentful client tweaks (#351)

* Avoid waiting for complete response, if we are just checking if for success status code. Avoid evaluating OS & Version for every request. Avoid a possible MemoryStream leak. Other minor tweaks

* Dispose responses & requests, pass cancellationToken & avoid an array allocation

* Dispose cloned request, add sealed & readonly

* Avoid deserializing into a string by deserializing directly from the response stream. Then deserialization can start immediately instead of waiting for the entire response. Reuse JsonSerializerSettings. Avoid async Task methods where it adds no value.

* Use HTTP/2

* Allow HTTP response connection

* Update package and dependency
