Is your feature request related to a problem? Please describe.
Given the modern fabric solution of presenting multiple services on a single port, we'd like the option to tag a given peering VLAN onto a fabric port with a customer-selected VLAN ID. This type of port-specific VLAN hand-off is common place in modern switching platforms and is easily automated with the correct source-of-truth information.

Describe the solution you'd like
During provisioning, when a user selects "Use 802.1q framing" they are presented with an additional field (portSpecificVlanId) where they can select a VLAN ID to hand the peering VLAN off on.

Note: we currently have this partially working in our own fork, some work is required to align with master and updated all the associated function (e.g. provisioning YAML output etc.)
