fail to deal with request header Expect: 100-Continue and respone

hi @pintsized , #### Bug 1 the following point is case sensitive,so if the value of request header Expect has some upper character,we will make mistake without handle_continue; - [http.lua#L539](https://github.com/pintsized/lua-resty-http/blob/master/lib/resty/http.lua#L539)...

get_client_body_reader should add support for chunked request body

Hi @pintsized `get_client_body_reader` return nil for a chunked request body. it's because `ngx.req.socket` is not yet support chunked request body. however,i think lua-resty-http should fix the case with `ngx.req.read_body`. thanks.

[Advise]the improvement on roundrobin.
