xci: Fix network configuration

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.
