Bring the setup_common() from CCv0 branch test's integration/kubernetes/confidential/tests_common.sh. It should be used to reduce boilerplates on the setup() of the tests. Unlike the original code, this won't export the `test_start_time` variable as it wouldn't be accurate to grab logs from the worker nodes due date/time mismatch between the running tests machine and the worker node. The function export the `node` variable which holds the name of a random node which has kata installed. Apart from that, it exports the `node_start_time` which capture the date/time when the test started, relative to the `node`. Tests that should inspect the logs can schedule pods/resources to the `node` and use `node_start_time` as the value reference to grep the logs.
