Merge branch 'test/reboot_between_unit_test_cases' into 'release/v2.0'

CI: add reset between running each unit test cases

Unit test is designed to detect bug **within** each test case. Therefore we'll reset between each case to provide a clean context. We will later add stress cases to run unit test cases together to detect potential bugs.

See merge request !636
