BUG/MINOR: lua/httpclient: missing free in hlua_httpclient_send()
In hlua_httpclient_send(), we replace hc->req.url with a new url.
But we forgot to free the original url that was allocated in
hlua_httpclient_new() or in the previous httpclient_send() call.
Because of this, each httpclient request performed under lua scripts would
result in a small leak. When stress-testing a lua action which uses httpclient,
the leak is clearly visible since we're leaking severals Mbytes per minute.
This bug was discovered by chance when trying to reproduce GH issue #2037.
It must be backported up to 2.5
