    Move state reporting initialization to after worker forking

    We start state reporting thread before forking child processes. This
    leads to possibility of fork in the middle of reporting process. This
    can cause child processes to start with corrupted global state. In [0]
    it represented itself as metadata agent not being able to make RPC call
    because of lock acquired in main process before fork and released after
    fork. See bug description for details.
