   * Consider a hypothetical node pool with 5 nodes having maxSurge=2,

   * simultaneously. It creates 2 additional (upgraded) nodes, then it brings
   * down 3 old (not yet upgraded) nodes at the same time. This ensures that
   * there are always at least 4 nodes available.
   * These upgrade settings configure the upgrade strategy for the node pool.
   * Use strategy to switch between the strategies applied to the node pool.
   * If the strategy is ROLLING, use max_surge and max_unavailable to control
   * the level of parallelism and the level of disruption caused by upgrade.
   * 1. maxSurge controls the number of additional nodes that can be added to
   * the node pool temporarily for the time of the upgrade to increase the

   * 2. maxUnavailable controls the number of nodes that can be simultaneously
   * unavailable.
   * 3. (maxUnavailable + maxSurge) determines the level of parallelism (how
   * many nodes are being upgraded at the same time).
   * If the strategy is BLUE_GREEN, use blue_green_settings to configure the
   * blue-green upgrade related settings.
   * 1. standard_rollout_policy is the default policy. The policy is used to
   * control the way blue pool gets drained. The draining is executed in the

   * time after each batch gets drained.
   * 2. node_pool_soak_duration is the soak time after all blue nodes are
   * drained. After this period, the blue pool nodes will be deleted.

     *
     * <pre>
     * These upgrade settings control the level of parallelism and the level of
     * disruption caused by an upgrade.
     * maxUnavailable controls the number of nodes that can be simultaneously
     * unavailable.
     * maxSurge controls the number of additional nodes that can be added to the
     * node pool temporarily for the time of the upgrade to increase the number of
     * available nodes.
     * (maxUnavailable + maxSurge) determines the level of parallelism (how many
     * nodes are being upgraded at the same time).
     * Note: upgrades inevitably introduce some disruption since workloads need to
     * be moved from old nodes to new, upgraded ones. Even if maxUnavailable=0,
     * this holds true. (Disruption stays within the limits of
     * PodDisruptionBudget, if it is configured.)
     * Consider a hypothetical node pool with 5 nodes having maxSurge=2,
     * maxUnavailable=1. This means the upgrade process upgrades 3 nodes
     * simultaneously. It creates 2 additional (upgraded) nodes, then it brings
     * down 3 old (not yet upgraded) nodes at the same time. This ensures that
     * there are always at least 4 nodes available.
     * These upgrade settings configure the upgrade strategy for the node pool.
     * Use strategy to switch between the strategies applied to the node pool.
     * If the strategy is ROLLING, use max_surge and max_unavailable to control
     * the level of parallelism and the level of disruption caused by upgrade.
     * 1. maxSurge controls the number of additional nodes that can be added to
     * the node pool temporarily for the time of the upgrade to increase the
     * number of available nodes.
     * 2. maxUnavailable controls the number of nodes that can be simultaneously
     * unavailable.
     * 3. (maxUnavailable + maxSurge) determines the level of parallelism (how
     * many nodes are being upgraded at the same time).
     * If the strategy is BLUE_GREEN, use blue_green_settings to configure the
     * blue-green upgrade related settings.
     * 1. standard_rollout_policy is the default policy. The policy is used to
     * control the way blue pool gets drained. The draining is executed in the
     * batch mode. The batch size could be specified as either percentage of the
     * node pool size or the number of nodes. batch_soak_duration is the soak
     * time after each batch gets drained.
     * 2. node_pool_soak_duration is the soak time after all blue nodes are
     * drained. After this period, the blue pool nodes will be deleted.
     * </pre>
