Add a new network template to the PVC cluster provisioner.
MAC address templates are used to provide predictable MAC addresses for provisioned VMs.
The normal format of a MAC template is:
{prefix}:XX:XX:{vmid}{netid}
The {prefix} variable is replaced by the provisioner with a standard prefix ("52:54:01"),
which is different from the randomly-generated MAC prefix ("52:54:00") to avoid accidental
overlap of MAC addresses.
The {vmid} variable is replaced by a single hexidecimal digit representing the VM's ID,
the numerical suffix portion of its name; VMs without a suffix numeral have ID 0. VMs with
IDs greater than 15 (hexidecimal "f") will wrap back to 0.
The {netid} variable is replaced by the sequential identifier, starting at 0, of the
network VNI of the interface; for example, the first interface is 0, the second is 1, etc.
The four X digits are use-configurable. Use these digits to uniquely define the MAC
address.
Example: pvc provisioner template network add --mac-template "{prefix}:2f:1f:{vmid}{netid}" test-template
The location of the two per-VM variables can be adjusted at the administrator's discretion,
or removed if not required (e.g. a single-network template, or template for a single VM).
In such situations, be careful to avoid accidental overlap with other templates' variable
portions.
