Create a VPC subnet

post https://api.linode.com/{apiVersion}/vpcs/{vpcId}/subnets

Create a VPC Subnet.

The User accessing this operation must have read_write grants to the VPC.
A successful request triggers a subnet_create event.

Once a VPC Subnet is created, it can be attached to a Linode by assigning the Subnet to one of the Linode's Configuration Profile Interfaces. This step can be accomplished with the following operations:

Create a Linode
Create a config profile
Update a config profile
Add a configuration profile interface

linode-cli vpcs subnet-create $vpcId \
  --label cool-vpc-subnet \
  --ipv4 10.0.1.0/24
