* lib/discovery/consul: update services on the watcher's start
Previously, watcher's start was only initing goroutines for discovery
but not waiting for the first iteration to end. It means first Consul
discovery wasn't returning discovered targets until the next iteration.
The change makes the watcher's start blocking until we get first discovery
iteration done and all registries updated.
