Fix "No such file or directory" problem when cleaning "veth*.ifstate" files (#3089)
Fix "No such file or directory" problem when cleaning "veth*.ifstate" files (#3089)

See #3081 for a discussion.

Let Ansible ignore errors from the `find` command because there is no option to let the `find` commmand ignore errors from the `-delete` action.

Root cause of the problem must be a race condition where files that have been identified during the `Find` phase have been removed before these files are processed in the `Action` phase.
