Subject: add tests and ci workflow for running tests

This commit adds tests (using python3 pytest framework):
1. Test basic accel-cmd commands (show version, show stat, etc)
2. Test ipoe shared session up (dhcpv4) without radius
3. Test pppoe discovery (without PADO delay)
4. Test pppoe discovery (without PADO delay)
5. Test pppoe session up (ipv4) without radius
6. Test vlan creation using vlan-mon (pppoe)

These tests require external utils. Please read tests/README.md how to setup
environment, how to run the tests and how to generate coverage report
Also, run-tests.yml contains step-by-step instruction how to run the tests
