Add QinQ support for IXIA traffic profile

Implemented logic for parsing and applying QinQ in IXIA traffic profile.
For QinQ configuration add QinQ section to outerl2 section.
For example:
...
  outerl2:
    QinQ:
      S-VLAN:
        id: 128
        priority: 0
        cfi: 0
      C-VLAN:
        id: 512
        priority: 0
        cfi: 0
...
