Description of PR

Summary:
Fixes #11744
test_encap_with_mirror_session would invoke fixture setup_mirror_session, and it would invoke fixture setup_uplink. There are steps in fixture setup_uplink, which could restart teamd docker, it would lead swss and syncd docker exits.
If the autorestart is disabled in test_pretest.py, then swss and syncd will fail to restart, and then leads to test failure.

This PR fixed the issue by adding a fixture to enable container autorestart before the test running.
