Currently, there is no way to specify a custom entrypoint or cmd for the underlying container associated with a device. However, in some scenarios, it is necessary to override or extend the default entrypoint to pass additional parameters or alter the container behavior.

Proposed Change:

Introduce support for two new metadata fields at the device level:

• entrypoint: to override the container's default entrypoint.
• cmd: to override or append arguments to the default command.

These fields should allow full control over how the container is started, and should integrate cleanly with the existing startup process.
