Debian ROCm CI: Worker telemetry

Description of the project: The Debian ROCm Team operates, a CI environment in which the ROCm software stack's unit tests are run on various AMD GPU architectures.

Workers run tests either on bare metal, or in containers, or in QEMU virtual machines. In all cases, collecting telemetry on GPU and system health during tests would provide information useful for maintaining system health at runtime as well as enabling higher-level analysis over time and system setups.
