    dht/rebalance: allocate migrator thread pool dynamically
    
    Problems: The maximum number of migratior threads created was static set
    to "40". And the number of these threads get created in rebalance depends
    on the number of cores user has. If the number of cores exceeds 40, a
    crash or memory corruption can be seen.
    
    Fix: Make the migratior thread pool dynamic.
