CuckooTable insertLoop stack overflow

[karulont]

We have a recursive algorithm for cuckoo table insert.
We do limit the recursion with maxEvictionCount value in the config. However, it turns out that there was an oversight. After recursively calling "expand" we reset the eviction count. This means that instead of doing only maxEvictionCount recursive calls, we are doing maxEvictionCount * number_of_expansions recursive calls.

We need to rewrite the insertLoop algorithm so that we have a proper upper bound on the recursion.
