class SectionStorageManager in Drupal 8

Provides the Section Storage type plugin manager.

Note that while this class extends \Drupal\Core\Plugin\DefaultPluginManager and includes many additional public methods, only some of them are available via \Drupal\layout_builder\SectionStorage\SectionStorageManagerInterface. While internally depending on the parent class is necessary, external code should only use the methods available on that interface.
