Kuryr uses the default subnet for the CIDR defined in the config file. Kuryr assumes the CIDR for the subnet is covered in the subnetpool created in advance and it should create anew subnets with the subnetpools.

However, current Kuryr just query the subnet with the subnetpools defined in the config file and it doesn't create new subnets. So it should examine the given CIDR for the endpoint creation can be covered by the subnetpools and create subnets if they don't exist. If they exist, it should resuse the pre-existing subnets instead.
