This patch enables PATCH support for the DateTime and DateTimeLocalOffset fields of the Redfish Manager resource in sushy-tools, allowing clients like sushy to update the BMC clock through the Redfish interface. Key changes: - In managers.py, added set_datetime() and get_datetime() methods in the FakeDriver class. These store and retrieve datetime values as instance attributes (not indexed by UUID), since each instance represents a single manager. - In main.py, added PATCH support in the Manager resource handler. Removed reset_cache() hook to preserve instance state across requests, enabling PATCH updates to persist. - In test_main.py, mocked get_datetime() return values to support unit tests for the datetime PATCH logic. - In test_managers.py, added a unit test for the set_datetime() and get_datetime() methods. Also includes a release note describing the new functionality. Change-Id: I91c671316d8c646fa6cd80c926a2c8b872a7a1fa
