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.
