Log stats for Optimize

OptimizeStats is crucial for us to tune our configuration for
optimization, which might affect the health of AppSearch and system
overall. Details can be found in Ib7ae475cc035d1b69969df1e22ac409895e0e3fa.

Also add sampling parameters in AppSearchConfig for:
1) initializeStats
2) searchStats
3) globalSearchStats
4) optimizeStats
