[TASK] Improve cache performance

Pages and TS cache may contain a lot of data. According to studies
found on the Internet, saving long BLOBs to the database may cause
a major performance decrease. Enable compression to make chunks of
page and TS caches smaller.

This patch enables compression for cache_pages and cache_pagesection.
