fix #553 Remove the deprecated HttpClient#chunkedTransfer

[violetagg]

By default Transfer-Encoding: chunked will be applied for those HTTP methods
for which a request body is expected. If the user wants to disable that setting
then the user can provide Content-Length via request headers and
thus Transfer-Encoding will be removed.
