commit 5bbb92f9b6a99b5cf4aff0e62a592f5702c7cbb4

    20227: Change default BalacePeriod to 6 hours.
    
    This matches BalanceTimeout.
    
    The previous time of 10 minutes was much to short, since sweeps are
    not incremental, a full sweep on a moderately sized cluster could
    easily take 8 minutes out of the 10 minute interval meaning
    keep-balance would be running almost constantly.
    
    Add upgrading note about keep-balance.

+Important!  This upgrade includes a database schema update changing the integer id column in each table from 32-bit to 64-bit.  Because it touches every row in the table, on moderate to large sized installations this may be very slow (on the order of hours).
