Debian ROCm CI: New frontend

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

The current frontend is provided by Debian's own CI software, debci. However, this frontend is optimized for navigating and displaying information for tens of thousands of packages for a particular operating system (such as Debian or Ubuntu).

Our own CI environment is only interested in a few dozen packages relevant to ROCm: the ROCm libraries, and all of their reverse dependencies, such as ?PyTorch or Blender.

Furthermore, we'd like to see information that is not part of the current frontend, such as: worker status (including metadata), summary of the most recently run tests, visualizations of worker queues, and so on.
