nova-manage floating list returns error if no floating IPs

[Lorin Hochstein]

Version: Diablo (2011.3.1)

If there are no floating IPs, "nova-manage floating list" returns an error message:

# nova-manage floating list
Command failed, please check log for more info

Would improve usability if it returned a message that said "No floating IPs have been defined".

    Print friendly message if no floating IPs exist.

    Fix bug 932071.

    Print out a friendly message from nova-manage when the "floating list"
    command is issued but no floating IPs have been defined. Prior to this
    change, a generic error message would be printed, pointing to the log
    for further details.
