Title: crush: add a new flag HASHPSPOOL2 for the congruential pps algorithm

We did some optimization for the issue of unbalanced pg distribution among osds in previous work. Please refer to #2402 for details.

In this commit, we updated codes for adding a new hashpspool flag HASHPSPOOL2 for the new congruential pps hash algorithm as per previous comments.
