To run functional tests on GH runners, we need to use LXD juju substrate. However only Juju 3.1+ supports createing LXD VMs (need by the functional test). Rather than bringing Juju 3 support to stable/yoga branch of zaza and zaza-openstack-tests, it is easier for us to switch to stable/caracal branch that already supports Juju 3.

When env. variable 'TEST_SKIP_PROMETHEUS' is exported, the prometheus exporter test is skipped. This allows older releases of OVN charms to use stable/caracal branch of zaza-openstack-tests and benefit from the Juju3 support. Signed-off-by: Martin Kalcok <[email protected]>
When env. variable 'TEST_SKIP_HW_OFFLOAD' is exported, the Hardware Offload test is skipped. This allows older releases of ovn-dedicated-chassis charm, which lack the HW offload support, to use stable/caracal branch of zaza-openstack-tests and benefit from the Juju3 support.

In order to use GH runners for functional tests of OVN chassis charms, we need the support for LXD VMs in Juju. This feature is supported since 3.1, but unfortunately,
zazaandzaza-openstack-testsinstable/yogabranch don't support Juju3.A solution for
22.03releases ofovn-chassisandovn-dedicated-chassis, which until now used zazastable/yoga, is to upgrade zaza tostable/caracal. This works fine in general and brings us a lot of fixes that were already backported to this branch, but we need to make couple tests optional, because the functionality is not present in22.03version of charms. Optional tests are controlled via environment variables.TEST_SKIP_PROMETHEUSskips test for reachability of prometheus exporterTEST_SKIP_HW_OFFLOADskips test for "Hardware offload"
