MINOR: pools: evict excess objects using pool_evict_from_local_cache()

Till now we could only evict oldest objects from all local caches using
pool_evict_from_local_caches() until the cache size was satisfying again,
but there was no way to evict excess objects from a single cache, which
is the reason why pool_put_to_cache() used to refrain from putting into
the local cache and would directly write to the shared cache, resulting
in massive writes when caches were full.

Let's add this new function now. It will stop once the number of objects
in the local cache is no higher than 16+total/8 or the cache size is no
more than 75% full, just like before.

For now the function is not used.
