Describe the bug
I'm having a Gateway Device and a connected child-device with tedge-agent running on both. When onboarding it the first time to a Cumulocity tenant, everything works well and all supported Operations by the tedge-agent (e.g. config management, log file management, etc) are shown in the UI.

After moving the Devices to another tenant, the child-device in Cumulocity does not have any c8y_SupportedOperations fragment, thus the UI does not offer everything the tedge-agent could do.

To Reproduce

• Onboard Device + Child-Device to Tenant A
• Remove certificate from main device and onboard it to another Tenant B
• Check the c8y_SupportedOperations fragment of the child-device in Tenant B

Environment (please complete the following information):

• OS: Debian Bookworm
• Hardware: RPI5/4
• System-Architecture: aarch64
• thin-edge.io version: 1.5.1

Additional context
The problem seems to be caused by a Cache that only submits the c8y_SupportedOperations fragment on change. One can get the supported operations set by:

• delete any inbuilt operation file (e.g: c8y_Restart ) of that child device from the /etc/tedge/operations/c8y/<child-device-id>/ directory on the main device
• restart the tedge-agent on child device.
