Migrate queue importer

This module provides the ability to create cron migrations(configuration entities) with a reference towards migration entities in order to import them during cron runs. You can also define additional options such as update and ignore dependencies for each of the referenced migrations.

Similar modules:

• Migrate Cron
• Migrate Scheduler

I know these modules implement the same functionality, but none of them use the Queue API, meaning each cron run is a potential timeout in case you have voluminous migration sources. The hook_cron() defined in the module is not executed from the cron settings form to avoid the same outcome.

I should mention that the Cron Migration entity code is taken from this issue, so special thanks to HenkeM.

The cron migration entities are exportable, meaning that you can deploy them to other environments/projects.
Another use case would be to isolate specific cron migrations using the Config Split module.
