If not for "Storage network" role, how would we default which network to 
use. In fact, we are planning to remove the drop down to choose network 
from the Add Brick UI, to avoid confusion and just use the network with 
this role, if available - otherwise use the host address. (host_address 
in vds_static)

Will update page accordingly

Could this network be reused for other storage needs also. If not, we 
can rename it "gluster network"
