Migrate release data script to new backend module

[preaction]

We need to migrate the release data script to the new backend module system. The old code is located in old/release.

This code does the following:

1. Update the release_data table to contain a single row for every test summary row in the cpanstats table. This row contains a 1 in one of the test grade columns (pass, fail, na, unknown).
2. Update the release_summary table to contain a single entry for every dist+version (a release). This row should contain a count of all the pass, fail, na, unknown reports for the release.

For example, here's the difference between the data in the two tables:

mysql> select * from release_data limit 5;

All of the tables required by this script are already managed by CPAN::Testers::Schema:

• https://metacpan.org/pod/CPAN::Testers::Schema::Result::ReleaseStat - The release_data table
• https://metacpan.org/pod/CPAN::Testers::Schema::Result::Release - The release_summary table
• https://metacpan.org/pod/CPAN::Testers::Schema::Result::Stats - The cpanstats table

The only useful end result in the data in the release_summary table. If we can build this table without leaving intermediary data around, that would be great.

This code should be in a new module, CPAN::Testers::Backend::Release. This module should use the Beam::Runnable role. The process should be configured in etc/container/report.yml. It should be configured to run every hour via cron in the Rexfile. Then the old process should be disabled to prevent erroneous data.

In addition to updating the newly-added data, there should be an option to rebuild all of this data from scratch, completely clearing all derived data in release_data and release_summary and building them back up.

[preaction]

The existing code is broken subtly: It considers a distribution to be a "dev" release (distmat) only if the version contains a "_". This is incorrect, there are also -TRIAL releases. The CPAN::DistnameInfo does this correctly, and we should use that.
