Always attempt to delete entire floating IP range.
Always attempt to delete entire floating IP range.

Fix bug 1021222.

This patch tweaks nova-manage to always attempt to delete all addresses
in the specified IP range, even if an error is encountered.  This is an
easy way to handle a case where a range was created, but then a subset
of that range was deleted.  Otherwise, deleting the rest of the range is
a pain.

An example of this would be:

  # nova-manage floating create --ip_range=1.1.1.0/24
  # nova-manage floating delete 1.1.1.1
  # nova-manage floating delete 1.1.1.0/24

Previously this would fail.  Now it works.
