virt_net: idempotency of create/stop actions (#53276)

Currently, if we try to stop or start a network two time in a row, the
second call will fail. With this patch:

- we don't recreate a network, if it exists
- we only stop a network if it's active, and so we avoid an exception
  saying the network is not active

* test: mock libvirt

* add integration tests for virt_net

* test: enable virt_net test on RedHat 7 and 8

* ci: use the unsupported alias

* tests that require privileged mode are run in VM

* virt_net/create raise unexpected libvirt exception

* import mock from units.compat

* virt_net: do not call create() on "active" network

* virt_net func test: only clean up the libvirt packages

* test: virt_net: don't use assert_called()

* virt_net: add the destructive alias

* move the test in virt_net dir

* test/virt_net: clean up the network at the end
