Starting from v1.5.0 of the exporter, OS_COMPUTE_API_VERSION can be set to configure the Nova API version to be used [1]. Microversion 2.1 can be used to keep metrics unmodified from the previous exporter version deployed by Kolla (v1.3.0). Support it with prometheus_openstack_exporter_compute_api_version, defaulting to using the latest version.
