Fix URL length for alembic migrations
So, even though this was the initial state of the database. Having the URL as 500 makes the creation of the database break in InnoDB databases. This is because InnoDB databases have the hard limit that indexes should be of a length of 767 bytes maximum. Now, the 'values_index' index is of 36 (container_id) + 255 (name) + 500 (URL) which is bigger than 767 (791 in total actually). So this CR sets that as 255, to avoid that. The reason of choosing 255 as the length of the URL, is because that is the value that the model has currently. So that value appears both in the current model [1] and a migration script [2].
