Get the default values for various cluster properties.

## Response `200`

Success.

- ClusterDefaultConfig
  - `cluster_network_cidr` string
  - `cluster_network_host_prefix` integer
  - `inactive_deletion_hours` integer
  - `service_network_cidr` string
  - `ntp_source` string
  - `cluster_networks_ipv4` ClusterNetwork[]
    - `cluster_id` string, uuid — The cluster that this network is associated with.
    - `cidr` string
    - `host_prefix` integer — The subnet prefix length to assign to each individual node. For example if is set to 23, then each node is assigned a /23 subnet out of the given CIDR, which allows for 510 (2^(32 - 23) - 2) pod IPs addresses.
  - `cluster_networks_dualstack` ClusterNetwork[]
    - `cluster_id` string, uuid — The cluster that this network is associated with.
    - `cidr` string
    - `host_prefix` integer — The subnet prefix length to assign to each individual node. For example if is set to 23, then each node is assigned a /23 subnet out of the given CIDR, which allows for 510 (2^(32 - 23) - 2) pod IPs addresses.
  - `service_networks_ipv4` ServiceNetwork[]
    - `cluster_id` string, uuid — A network to use for service IP addresses. If you need to access the services from an external network, configure load balancers and routers to manage the traffic.
    - `cidr` string
  - `service_networks_dualstack` ServiceNetwork[]
    - `cluster_id` string, uuid — A network to use for service IP addresses. If you need to access the services from an external network, configure load balancers and routers to manage the traffic.
    - `cidr` string
  - `forbidden_hostnames` string[] — This provides a list of forbidden hostnames. If this list is empty or not present, this implies that the UI should fall back to a hard coded list.
