/** Extensible load balancing policy configuration.
  *
  * Every LB policy defined via this mechanism will be identified via a unique name using reverse
  * DNS notation. If the policy needs configuration parameters, it must define a message for its
  * own configuration, which will be stored in the config field. The name of the policy will tell
  * clients which type of message they should expect to see in the config field.
  *
  * Note that there are cases where it is useful to be able to independently select LB policies
  * for choosing a locality and for choosing an endpoint within that locality. For example, a
  * given deployment may always use the same policy to choose the locality, but for choosing the
  * endpoint within the locality, some clusters may use weighted-round-robin, while others may
  * use some sort of session-based balancing.
  *
  * This can be accomplished via hierarchical LB policies, where the parent LB policy creates a
  * child LB policy for each locality. For each request, the parent chooses the locality and then
  * delegates to the child policy for that locality to choose the endpoint within the locality.
  *
  * To facilitate this, the config message for the top-level LB policy may include a field of
  * type LoadBalancingPolicy that specifies the child policy.
  *
  * @param policies
  *   Each client will iterate over the list in order and stop at the first policy that it
  *   supports. This provides a mechanism for starting to use new LB policies that are not yet
  *   supported by all clients.
