Manages migration plugins.

Analyzes migration definitions to ensure that the source plugin of any migration tagged with particular tags ('Drupal 6' or 'Drupal 7' by default) defines a source_module property in its plugin annotation. This is done in order to support the Migrate Drupal UI, which needs to know which modules "own" the data being migrated into Drupal 8, on both the source and destination sides.

@todo Enforce the destination_module property too, in https://www.drupal.org/project/drupal/issues/2923810.
