  - xci: Fix network configuration

    This change
    - sets static IP for controller nodes' vxlan bridges as stated
    in osa documentation: compute and network hosts must have an IP [1]
    - configures IPs for controller nodes' vxlan bridges.
    - removes the additional vlan ip from compute nodes as it seems to
    be there for all in one.
    - removes glean.rules as they mess with the network configuration once
    the network changes are applied.
    - removes the contents of interfaces.d as osa populates config for
    lxc bridges and includes this config in interfaces file thus all the
    files in interfaces.d must be removed in order not to mess with the
    network configuration.
    - updates modules appropriately.
