Simplify/correct network args in server create

Refs: #4563

In server create, replace network arguments with only two:

--network=[id=]NETWORK_ID[,[ip=]IP]
--no-network  (flag)

There arguments are mutually exclussive
Add --diagnostics to server info
Always use "details" call in neworks/subnets list
Restore server console
Remove --vnc option from server info
Reverse server create --no-network/None http req

From now on, --no-network produces a "networks=[]" part,
while the absense of network-related arguments makes produces a
request without "networks" attributes.
Update wait to use --status
