Instance Type represents a high-level tier or SKU of the service that this instance belong to. When enabled(eg: Maintenance Rollout), Rollout uses 'instance_type' along with 'software_versions' to determine whether instance needs an update or not.
   *   `labels` (*type:* `map()`, *default:* `nil`) - Optional. Resource labels to represent user provided metadata. Each label is a key-value pair, where both the key and the value are arbitrary strings provided by the user.
   *   `maintenancePolicyNames` (*type:* `map()`, *default:* `nil`) - Deprecated. The MaintenancePolicies that have been attached to the instance. The key must be of the type name of the oneof policy name defined in MaintenancePolicy, and the referenced policy must define the same policy type. For complete details of MaintenancePolicy, please refer to go/cloud-saas-mw-ug.
