Module loadbalance 

Available on crate feature client only.

HTTP Loadbalance Layer

This is a copy of volo::loadbalance::layer without the retry logic. Because retry needs the Req has Clone trait, but HTTP body may be a stream, which cannot be cloned. So we remove the retry related codes here.

In addition, HTTP service can use DNS as service discover, so the default load balance uses a DNS resolver for pick a target address (the DNS resolver picks only one because it does not need load balance).
