Krishnan Parthasarathi 85c6bb9809 server: Sort disk arguments for consistent ordering (#3469)
This is important in a distributed setup, where the server hosting the
first disk formats a fresh setup. Sorting ensures that all servers
arrive at the same 'first' server.

Note: This change doesn't protect against different disk arguments
with some disks being same across servers.
