[test gap] Enhance the existing incremental ACL test

[bingwang-ms]

Description

The test is to verify dataplane ACL works as expected after excessive update. The existing TestIncrementalAcl did some incremental test, but not enough to cover the real scenario in production. https://github.com/sonic-net/sonic-mgmt/blob/8ba7efab4a8eb1565a79e5aeeb0b760330aca24f/tests/acl/test_acl.py#L1061

Test steps

1. Configure some ACL rule on the box. We call it original rules
2. Do multiple (say 1000 times) insertion/deletion on the testing ACL table.
3. Verify the original rules work as expected.
4. Add new ACL rules, and verify it works as expected.
5. Verify no crash happened.
