create new OAM vlan with new subnet range for provisioning new ceph
We need to expand the network capacity available for provisioning services in MAAS+juju. This specifically relates to provisioning the new ceph cluster using a dedicated vlan and IP range. This vlan needs to replace the untagged oam vlan 2060 on the ceph nodes and be distributed to the infra nodes as a tagged vlan on the data nic (100G).
