test network configuration broken with openvswitch bridge

[Chris MacNaughton]

Testing maas 2.9 + openvswitch bridges, when I try to use the "validate network config" functionality, my tests fail with :

/etc/netplan/netplan.yaml:28:7: Error in network definition: br-ex.1001: The 'ovs-vsctl' tool is required to setup OpenVSwitch interfaces.

MAAS version: 2.9.1 (9153-g.66318f531)

I setup ovs by creating a bond in MAAS (eno3+4), and then adding an openvswitch bridge to that bond.

After creating the bridge, I clicked the "Validate network configuration" button and accepted the default set of tests and parameters:
internet, gateway, and rack-controller connectivity tests with 'https://connectivity-check.ubuntu.com' as the URl for the internet connectivity script.

MAAS needs to include openvswitch-switch package in the ephemeral environment it uses for Testing when the user has picked an OVS bridge

This is still happening and not fixed yet. Would be great if we can fix this. I tested this with MAAS 3.2.6 (Snap).

Apparently all we need is having the Openvswitch packages installed prior to netplan apply.

Unfortunately it's not just the openvswitch packages, since the OVS kernel modules are also needed.

Currently we don't install the kernel and modules in the ephemeral environment, since the kernel+initrd is passed by maas directly as boot, so we need to either add OVS modules to the initrd, or install kernel+modules (along with their deps) in the ephemeral env
