Allows altering the list of discovered migration plugins.

Modules are able to alter specific migrations structures or even remove or append additional migrations to the discovery. For example, this implementation filters out Drupal 6 migrations from the discovered migration list. This is done by checking the migration tags.

Parameters

array[] $migrations: An associative array of migrations keyed by migration ID. Each value is the migration array, obtained by decoding the migration YAML file and enriched with some meta information added during discovery phase, like migration 'class', 'provider' or '_discovered_file_path'.
