Code review comment for ~al3jandrosg/charm-telegraf:LP1976521

Lots of func test issues due to charmcraft problems. Eventually
managed to get that going and the Zaza model deployed
correctly with the below versioning on a Focal host:

sudo apt update; sudo snap refresh lxd --channel=5.0/stable; mkdir -p ~/.local/share/juju
sudo snap install juju --channel=3.1/stable --classic
juju bootstrap localhost controller; juju add-model test

sudo snap install charmcraft --channel=2.0/stable --classic
sudo apt install -y make tox

git clone https://git.launchpad.net/charm-telegraf; cd charm-telegraf
make functional

However, this now fails as neutron-gateway is unable to start
because of the below:

Feb 8 10:37:22 juju-32f109-7 ovs-ctl[9436]: modprobe: FATAL: Module openvswitch not found in directory /lib/modules/5.4.0-169-generic

However, this is not related to the patch (the steps above
fail with the out-of-the-box charm), hence why I submitted
it as is. I did check that the patch was working, i.e.,
permissions changed correctly, charm config options doing
their job.
