/**
 * Provides an interface for an Action plugin.
 *
 * @todo WARNING: The action API is going to receive some additions before
 * release. The following additions are likely to happen:
 *  - The way configuration is handled and configuration forms are built is
 *    likely to change in order for the plugin to be of use for Rules.
 *  - Actions are going to become context-aware in
 *    https://www.drupal.org/node/2011038, what will deprecated the 'type'
 *    annotation.
 *  - Instead of action implementations saving entities, support for marking
 *    required context as to be saved by the execution manager will be added as
 *    part of https://www.drupal.org/node/2347017.
 *  - Actions will receive a data processing API that allows for token
 *    replacements to happen outside of the action plugin implementations,
 *    see https://www.drupal.org/node/2347023.
