The common http api client class used by the scaleway modules only
enables automatic jsonification of the request body if the
"Content-Type" header is application/json. The client only included
"Content-type" in its default set of headers (notice the case
variation).
This caused a KeyError on send() if the caller relied on the default
content-type value.
