vyos.ifconfig: T1579: remove calls to vyos.ifconfig.Interface.get_config()
Interface.get_config() was always a pure helper which exposed a "per interface type" dictionary which was then fed by the caller to create interfaces by iproute2 which required additional options during creation time. Such interfaces had been: * tunnel * vxlan * geneve * macsec * wifi * macvlan / pseudo-ethernet The code was always duplicated to convert from the VyOS CLI based get_config_dict() to a dict which can be used to feed iproute2. This path has been removed and we now always feed in the entire dictionary retrieved by get_config_dict() or in the interfaces case, it's high-level wrapper get_interface_dict() to the interface we wan't to create. This also adds the - personally long awaited - possibility to get rid of the derived tunnel classes for e.g. GRE, IPIP, IPIP6 and so on.
