Supply persistent information to libEnsemble:

persis_info: [dict]:
    Dictionary containing persistent info

Holds data that is passed to and from workers updating some state information. A typical example is a random number generator to be used in consecutive calls to a generator. Optional.

If worker i sends back persis_info, it is stored in persis_info[i]. This functionality can be used to, for example, pass a random stream back to the manager to be included in future work from the allocation function.
