Unable build an instance of the Consul client with a custom HTTP connector

[LeonHartley]

While attempting to use turmoil with this Consul client, we noticed that you can't override the hyper HTTP connector that gets used when building the hyper client.

It'd be nice if we could override the whole process of building the HTTP client, and not just the builder, so we can use this library with turmoil, e.g:

rs-consul/src/lib.rs

Lines 255 to 256 in e18ce70

	let https = https_connector();
	let https_client = config.hyper_builder.build::<_, hyper::Body>(https);
