[ceph] Allow overriding ssh and storage_mgmt

To allow BM SNO with ceph using custom ceph CIDR values,
make ssh_network_range and storage_mgmt_network_range overridable via
cifmw_ceph_ssh_network_range and cifmw_ceph_storage_mgmt_network_range.
Both are set in set_fact which clobbers extra vars, so we use the
cifmw_ indirection with default() to preserve original defaults.

NOTE: storage_network_range also needs this treatment.
It use to be commented out in set_fact, and this change needs
extra testing with Ceph ci jobs perhaps.

Also gather network facts for IP-to-host mapping.
