    * The possible values are:

    *                  is selected in round robin order.
    *
    * * 'LEAST_REQUEST': An O(1) algorithm which selects two random healthy
    *                    hosts and picks the host which has fewer active requests.
    *
    * * 'RING_HASH': The ring/modulo hash load balancer implements consistent
    *                hashing to backends. The algorithm has the property that the
    *                addition/removal of a host from a set of N hosts only affects
    *                1/N of the requests.
    *
    * * 'RANDOM': The load balancer selects a random healthy host.
    *
    * * 'ORIGINAL_DESTINATION': Backend host is selected based on the client
    *                           connection metadata, i.e., connections are opened
    *                           to the same address as the destination address of
    *                           the incoming connection before the connection
    *                           was redirected to the load balancer.
    *
    * * 'MAGLEV': used as a drop in replacement for the ring hash load balancer.
    *             Maglev is not as stable as ring hash but has faster table lookup
    *             build times and host selection times. For more information about
    *             Maglev, refer to https://ai.google/research/pubs/pub44824
    *
    * * 'WEIGHTED_MAGLEV': Per-instance weighted Load Balancing via health check
    *                      reported weights. Only applicable to loadBalancingScheme
    *                      EXTERNAL. If set, the Backend Service must
    *                      configure a non legacy HTTP-based Health Check, and
    *                      health check replies are expected to contain
    *                      non-standard HTTP response header field

    *                      processed health check replies, as long as every
    *                      instance either reported a valid weight or had
    *                      UNAVAILABLE_WEIGHT. Otherwise, Load Balancing remains
    *                      equal-weight.
    *
    * * 'WEIGHTED_ROUND_ROBIN': Per-endpoint weighted round-robin Load Balancing using weights computed
    *                           from Backend reported Custom Metrics. If set, the Backend Service
    *                           responses are expected to contain non-standard HTTP response header field
    *                           X-Endpoint-Load-Metrics. The reported metrics
    *                           to use for computing the weights are specified via the
    *                           backends[].customMetrics fields.
    *
    * locality_lb_policy is applicable to either:
    *

    *   Load Balancing). Only MAGLEV and WEIGHTED_MAGLEV values are possible for External

    *
    * If session_affinity is not NONE, and locality_lb_policy is not set to MAGLEV, WEIGHTED_MAGLEV,
