Javi Martín 7c0e499eee Add table to store stats versions
We need a way to manually expire the cache for a budget or poll without
expiring the cache of every budget or poll.

Using the `updated_at` column would be dangerous because most of the
times we update a budget or a poll, we don't need to regenerate their
stats.

We've considered adding a `stats_updated_at` column to each of these
tables. However, in that case we would also need to add a similar column
in the future to every process type whose stats we want to generate.
