When an interface is being reconfigured with different bridge vlan settings, this makes old vlan IDs on the interface removed. This also makes the PVID= setting support negative boolean value, e.g. "no", in which case, the currently assigned PVID (typically, assigned by the kernel when an interface is joined to a bridge) is dropped. This feature is requested by #15291. Note, if a .network file has no settings about bridge vlan, networkd keeps the currently assigned vlan IDs. That's intended, to make not break existing setups. When a .network file has only PVID=no line in [BridgeVLAN] section, then all assigned vlan IDs are removed. Fixes #29975. Closes #15291.
