  - [POLICY] legacy PDP healtchcheck removed

    It may be causing some flakiness with some healthchecks
    passing in OOM builds.   Not sure the root cause, as the
    problem happens occassionally, may be a race condition or
    something else (legacy PDP and dependent components may
    take some time to initialize).
