This ensures the metrics proxy endpoint is ACL protected behind a
wildcard service:read and node:read set of rules. For Consul
Enterprise these will need to span all namespaces:

service_prefix "" { policy = "read" }
node_prefix ""    { policy = "read" }

namespace_prefix "" {
  service_prefix "" { policy = "read" }
  node_prefix ""    { policy = "read" }
}

This PR contains just the backend changes. The frontend changes to
actually pass the consul token header to the proxy through the JS plugin
will come in another PR.
