**Which issue(s) this PR fixes**: Fixes fluent#4079 **What this PR does / why we need it**: For reasons such as the load on the CI execution environment, looks like that rotation detection is delayed and the test does not execute as expected. For this reason, this patch adds a wait to ensure to detect the rotation. Before the patch was introduced, tests failed about once every 20 to 50 times. After, the test was successful 500 consecutive times. **Docs Changes**: **Release Note**: Signed-off-by: Shizuo Fujita <fujita@clear-code.com> Signed-off-by: Kentaro Hayashi <hayashi@clear-code.com>
