Add lint process for verifying release summary table

[preaction]

The release summary data (CPAN::Testers::Schema::Result::Release) has many rows with incorrect relationships to the uploads table (via the uploadid column). We should write a runnable module (using Beam::Runnable) that check to see that all of the dist/version information in this table is correct to the uploadid it is linked to.

If the data is incorrect, the script should fix it, but only if there is only one possible dist/version in the uploads table (see #16). In either case, the script should print out the offending row and either say that it has fixed it (and write what uploadid it fixed it to) or say that it could not be fixed automatically (and say which uploadids were available, and print the upload rows).

This process should be configured in etc/container/schema.yml and run via cron on a nightly basis.
