cannot set nova.conf [workarounds] params by juju config

charm: openstack 2023.2
nova-compute: 28.0.1 channel 2023.2/stable
ubuntu: jammy .15.0-102-generic #112-Ubuntu SMP Tue Mar 5 16:50:32 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

According to https://bugs.launchpad.net/nova/+bug/2061569 I have to setup two workarounds to mitigate live-migration bug.
Reading the nova-compute configuration on https://charmhub.io/nova-compute/configuration?channel=2023.2/stable, can't find the parameter to use, in fact if I run

#juju config nova-compute config-flags="skip_cpu_compare_at_startup=true,skip_cpu_compare_on_dest=true"

it populates the [DEFAULT] section rather than the [workarounds] one as you can see here https://paste.ubuntu.com/p/2zgWjpPJSS/

Hi @macchese

The charm doesn't actually (currently) support setting workarounds from a config flag. This would need to be a new feature:

 * Add a config option "workarounds-config-flags"
 * Implement a Context to read those flags.
 * Wire the context into the resource_map so that they are available in nova.conf
 * Update the template(s) to read from the context and set flags in the [workarounds] section (like the current config-flags work).
