William Lallemand 746e6f3f8e MINOR: httpclient/lua: supports headers via named arguments
Migrate the httpclient:get() method to named arguments so we can
specify optional arguments.

This allows to pass headers as an optional argument as an array.

The () in the method call must be replaced by {}:

	local res = httpclient:get{url="http://127.0.0.1:9000/?s=99",
	            headers= {["X-foo"]  = { "salt" }, ["X-bar"] = {"pepper" }}}
