A subnet with purpose set to PRIVATE_SERVICE_CONNECT is used to publish services using Private Service Connect. A subnet with purpose set to INTERNAL_HTTPS_LOAD_BALANCER is a proxy-only subnet that can be used only by regional internal HTTP(S) load balancers. Note that REGIONAL_MANAGED_PROXY is the preferred setting for all regional Envoy load balancers. If unspecified, the subnet purpose defaults to PRIVATE.

`stack_type`	`str` The stack type for the subnet. If set to IPV4_ONLY, new VMs in the subnet are assigned IPv4 addresses only. If set to IPV4_IPV6, new VMs in the subnet can be assigned both IPv4 and IPv6 addresses. If not specified, IPV4_ONLY is used. This field can be both set at resource creation time and updated using patch. Check the StackType enum for the list of possible values. This field is a member of `oneof`_ `_stack_type`.
`state`	`str` [Output Only] The state of the subnetwork, which can be one of the following values: READY: Subnetwork is created and ready to use DRAINING: only applicable to subnetworks that have the purpose set to INTERNAL_HTTPS_LOAD_BALANCER and indicates that connections to the load balancer are being drained.
