Olivier Houchard 8bc8a21b25 MEDIUM: stick-tables: Use a per-shard expiration task
Instead of having per-table expiration tasks, just use one per shard.
The task will now go through all the tables to expire entries. When a
table gets an expiration earlier than the one previously known, it will
be put in a mt-list, and the task will be responsible to put it into an
eb32, ordered based on the next expiration.
Each per-shard task will run on a different thread, so it should lead to
a better load distribution than the per-table tasks.
