According to PEP8, constants should be written in all capital letters.
This commit capitalizes these constants:
- thread_cert.TestCase.topology
- thread_cert.TestCase.support_ncp
- Update all test cases to inherit thread_cert.TestCase and update
topologies accordingly. The topologies should all be correct because
they are automatically generated, not hand written.
- Use default Thread version: 1.1
- Cleanup node tmp files in tmp directory according to the current
PORT_OFFSET in setUp. This is required by
test_reed_address_solicit_rejected.py and test_coap_observe.py since
they define multiple test functions in one TestCase.
- Removed call to set_extaddr64 because it's not necessary and causing
failures.
