/**
 * An interface for condition plugins.
 *
 * Condition plugins are context-aware and configurable. They support the
 * following keys in their plugin definitions:
 * - context: An array of context definitions, keyed by context name. Each
 *   context definition is a typed data definition describing the context. Check
 *   the typed data definition docs for details.
 * - configuration: An array of configuration option definitions, keyed by
 *   option name. Each option definition is a typed data definition describing
 *   the configuration option. Check the typed data definition docs for details.
 *
 * @todo Replace the dependency on \Drupal\Core\Form\FormInterface with a new
 *   interface from https://www.drupal.org/node/2006248.
 * @todo WARNING: The condition 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.
 *  - Conditions will receive a data processing API that allows for token
 *    replacements to happen outside of the plugin implementations,
 *    see https://www.drupal.org/node/2347023.
 *  - Conditions will have to implement access control for checking who is
 *    allowed to configure or perform the action at
 *    https://www.drupal.org/node/2172017.
