Better monitoring of Job's condition

[iszulcdeepsense]

Infrastructure plugins can now provide "infrastructure statistics" for every job. This is a JSON dictionary kept in a database that is displayed on a Dashboard:

Tested with https://github.com/TheRacetrack/plugin-kubernetes-infrastructure/pull/17, by running a pyhon job with:

class AdderModel:
    def perform(self, numbers: list[float]) -> float:
        ctypes.string_at(0)
        return sum(numbers)

Counter goes up each time perform is called. I tested using the generated swagger page.
