Unpin kubernetes in dagster-k8s
urllib3 doesn't accept the assert_hostname keyword argument anymore. Removing this configuration allows the integration tests to pass again, resolving https://github.com/dagster-io/dagster/issues/3111.
See https://github.com/rundeck-plugins/kubernetes/issues/4#issuecomment-712433065 for a discussion of the issue.
