mem-cache: Make cache warmup percentage a parameter.

The warmupPercentage is the percentage of different tags (based on the
cache size) that need to be touched in order to warm up the cache.
If Warmup failed (i.e., not enough tags were touched), warmup_cycle = 0.

The warmup is not being taken into account to calculate the stats (i.e.,
stats acquisition starts before cache is warmed up). Maybe in the future
this functionality should be added.
