selftests: concurrency: add test to verify concurrent delete
Implement test that verifies concurrent deletion of rules by executing 10 tc instances that delete flower filters in same handle range. In this case only one tc instance succeeds in deleting a filter with particular handle. To mitigate expected failures of all other instances, run tc with 'force' option to continue processing batch file in case of errors and expect xargs to return code '123' that indicates that invocation of command(s) exited with error in range 1-125.
