Configure Manila with an NFS network

Manila Tempest tests need to connect to the NFS share
for Ganesha tests, and they use a special (openstack)
network for that [1].

This patch adds an NFS network with VLAN 24 and range
172.21.0.0/24 in reproducers networking-definition.yml.
It also adds a multus range for this network so that the
Tempest pod can access this network for testing. The NFS
network is added to the OCP nodes for the same reason.
The podified-multinode-hci-deployment-crc job is updated
to not deploy manila since it was never tested by tempest.

This patch updates playbook manila_create_default_resources.yml
so that when CI for manila runs, a provider network is created.
Variables manila_provider_network_{name,vlan,start,end,range}
default to the storage network, but can be overridden to the
NFS network within a CI job definition.
