    Re-enable non-trunk baremetal test cases

    When baremetal trunk code was committed, test cases for baremetal
    non-trunk were disabled. This changeset turns them all back on.

    As part of trunk implementation, the 'is_native' flag is no longer
    pass in the transaction. Instead for non-trunk baremetal cases,
    the native vlan will always be configured on nexus. As a result, all
    test cases must additional check to verify if native vlan configuration
    is sent while the 'is_native' flag is removed from input transaction.
