* Advanced API to allow for multi-dimensional load balancing by remote
* server. For receiving LB assignments, the steps are:
* 1, The management server is configured with per cluster/zone/load metric
* capacity configuration. The capacity configuration definition is
* outside of the scope of this document.
* 2. Envoy issues a standard {Stream,Fetch}Endpoints request for the clusters
* to balance.
* Independently, Envoy will initiate a StreamLoadStats bidi stream with a
* management server:
* 1. Once a connection establishes, the management server publishes a
* LoadStatsResponse for all clusters it is interested in learning load
* stats about.
* 2. For each cluster, Envoy load balances incoming traffic to upstream hosts
* based on per-zone weights and/or per-instance weights (if specified)
* based on intra-zone LbPolicy. This information comes from the above
* {Stream,Fetch}Endpoints.
* 3. When upstream hosts reply, they optionally add header <define header
* name> with ASCII representation of EndpointLoadMetricStats.
* 4. Envoy aggregates load reports over the period of time given to it in
* LoadStatsResponse.load_reporting_interval. This includes aggregation
* stats Envoy maintains by itself (total_requests, rpc_errors etc.) as
* well as load metrics from upstream hosts.
* 5. When the timer of load_reporting_interval expires, Envoy sends new
* LoadStatsRequest filled with load reports for each cluster.
* 6. The management server uses the load reports from all reported Envoys
* from around the world, computes global assignment and prepares traffic
* assignment destined for each zone Envoys are located in. Goto 2.
