Add Storage NFS network for Manila to HCI Scenario

Manila tests need to connect to the share for both cephfs and ganesha tests, and they use a special (openstack) network for that [1]. This patch adds the NFS storage network (storagenfs) with VLAN 24 and range 172.21.0.0/24 in the HCI values example. The storagenfs network is configured on the HCI EDPM nodes and an NNCP, NAD, L2Advertisement and IPAddressPool are defined so that a pod in k8s can connect to it; such as the tempest pod which will perform storage tests. TODO: update Manila CRDs to use this network.
