selftests: concurrency: add test to verify concurrent replace

Browse Source 
Implement test that verifies concurrent replacement of rules by executing
10 tc instances that replace flower filters in same handle range.

Extend tdc_multibatch.py script with new optional CLI argument that is used
to generate all batch files with same filter handle range.
