roles/dch-storage-net: Set up/mount shared storage

Browse Source 
The *dch-storage-net* role configures a machine to connect the storage
network and mount shared folders from the storage appliance.

The `wait-global-address.sh` script and corresponding
*wait-global-address@.service* systemd unit template are necessary to
ensure that the storage network is actually available before attempting
to mount the shared volumes. This is particularly important at boot,
since `dhcpcd` does not implement any kind of signaling that can be used
by *network-online.target*, so the network is considered "online" as
soon as the `dhcpcd` process has started. This typically results in
"network unreachable" errors.
