3308279c4e lib/storage: remove outdated comment on maxRowsPerSmallPart 
The commend became outdated after the commit ed6ac1a5df027f0dfc22448e3b27c26b6f77c67a,
which stops merging of small parts on graceful shutdown instead of waiting
for their completion.

09fc6e22e5 all: use workingsetcache instead of fastcache 
This should reduce the amount of RAM required for processing time series
with non-zero churn rate.

The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.

5d8d110010 lib/fs: atomically create file with the given contents on WriteFileAtomically 
This should prevent from `transaction` and `metadata.json` files corruption
on unclean shutdown such as OOM, `kill -9`, power loss, etc.
