…containers to testcase (sonic-net#10070)

## Description of PR

Summary: Include multiasic scenario, add lldp and teamd containers to testcase
Fixes # (issue)

### Type of change

- [ ] Bug fix
- [ ] Testbed and Framework(new/improvement)
- [X] Test case(new/improvement)


## Approach
#### What is the motivation for this PR?
Handle both multiasic and single asic scenarios in container hardening testcase
Add lldp and teamd containers to testcase
#### How did you do it?
For teamd, the pattern `df -h` is different so cannot use `df -h | grep /etc/hosts | awk '{print $1}'` to grep device.

`/dev/vda3        16G  2.1G   14G  14% /var/warmboot`
#### How did you verify/test it?
Manual test
