Currently the following filters are written as though they support multiple values: * aggregate_image_properties_isolation.py * aggregate_instance_extra_specs.py * aggregate_multitenancy_isolation_filter * availability_zone_filter.py This commit adds support to the underlying helper method to support specifying multiple values separated by a comma. This change for example allows operators to set multiple tenants by using a comma separated list. eg. filter_tenant_id: "tenantid1,tenantid2" DocImpact: Closes-Bug: #1413087 Change-Id: I010e85ff4c29171c4be6d7a7209dbf2d55da0b64
