title: How to select namespace from Consul
body: <p>I have ent. Consul installed and it has multiple namespaces.
  I want to use Python module to query specified namespace. Basically if I have namespaces: ns_1, ns_2. I want get the services and respective meta for ns_1 and ns_2 individually.
  The input parameter would be the namespace (ns_1/ns_2).</p>
