Consul `Node.Name` might be a DNS name

Expected Behavior / New Feature

The consul service discovery provider should check if the node.Name could be a DNS/Host Name, otherwise return the service url.

Actual Behavior / Motivation for New Feature

The consul service provider doesn't check if the node.Name is a host name. Depending on service discovery configuration, the node.Name might not be a host name.

Node name: This is a unique name for the agent. By default, this is the hostname of the machine, but you may customize it using the -node flag.

Steps to Reproduce the Problem

1. Change the agent name, use something that is not related to the hostname.
2. Try to use the Consul Service Discovery
