  - Fix vlan network can't deploy instance

    JIRA: COMPASS-533

    Bug:
    When a vlan network is created and bind to a physical network,
    the instances launched on this network will fail to get ip
    address from openstack dhcp server.

    Solution:
    Set enable_isolated_metadata to True in dhcp_agent.in
