Steps to reproduce:
-Setup one node
-Click "add server"
-Enter IP address and type a 'space' at the end
-Click add
-First problem is that it tries to add the server anyway, it should fail at this point when it knows
-After trying to add the server, the error is: "Attention - Save request returned error."
The error doesn't mean anything to the user, this should be fixed.
We should also not accept servers with a space anywhere in the name since that is neither a valid DNS entry nor a valid IP address.
