  - [IDF] infra VMs: Allow trunking mgmt network

    Due to design limitations in idf.net_config, for a hybrid POD we need
    to trunk certain network segments for the VMs running on the
    jumpserver, including mgmt network going to cfg01, mas01.

    Add mgmt VLAN support for cfg01, mas01 gated by a flag in IDF:
      idf.fuel.jumphost.trunks.mgmt: True

    JIRA: FUEL-338
