This provides a workaround for a bug which affects empty body requests when sent with the Rest5Client configured to support http2.
The issue was introduced server side by elastic/elasticsearch#129302 and results in empty body requests causing the following exception:
Invalid media-type value on headers [Accept, Content-Type].(bonus: log fixes for Rest5Client)
