The source of truth is the local Nomad Agent. Any services not local that
have a matching prefix are removed. Changed services are re-registered
and missing services are re-added.
There were conflicting directives previously, both consul.addr and
consul.address were required to achieve the desired behavior. The
documentation said `consul.address` was the canonical name for the
parameter, so consolidate configuration parameters to `consul.address`.
Flattening and normalizing the various Consul config structures and
services has led to an import cycle. Break this by creating a new package
that is intended to be terminal in the import DAG.
