This commit adapts the GraphQlClient HTTP transports (async and sync) to accept 4xx responses if the response content type is "application/graphql-response+json". This allows the client to support the "GraphQL over HTTP" specification. This commit adds a new test suite to check compatibility against this spec. See gh-1117
