WIP [util] introduce TTL cache
This changelist introduces TTL cache based on the cache implementation
from util/cache.{h,cc} with FIFO eviction policy.
Expired entries are not returned from the cache, but kept around until
they are lazily purged upon cache reaching its capacity while
accommodating more entries.
WIP:
* introduce and update TTL-related metric gauges
* maybe, update the behavior of the cache
to purge expired items upon lookup
