limit connections to host

Not a very nice fix for #2248.
But at least something.

Wouldn't using 'curl' request option be a solution?

[Gemorroj]

@sagikazarmark this options for curl_init, not for curl_multi_init https://github.com/guzzle/guzzle/blob/master/src/Handler/CurlMultiHandler.php#L50

IMO we need a more elegant solution for that. A new option curl_multi (like 'curl' request option, but for curl_multi_init()/curl_multi_setopt()) is more flexible, since there are many CURLMOPT_* configuration constants available.

@sagikazarmark, @Gemorroj, put some code in #2287. Take a look.

#2287 looks better to me indeed
