 * Defines a base class from which other display classes may extend.

 * Plugins extending this class need to define a plugin definition array through
 * annotation. The definition includes the following keys:
 * - id: The unique, system-wide identifier of the display class.
 * - label: Human-readable name of the display class, translated.
 *
 * A complete plugin definition should be written as in this example:
 *
 * @code
 * @SearchApiDisplay(
 *   id = "my_display",
 *   label = @Translation("My display"),
 *   description = @Translation("A few words about this search display"),
 *   index = "search_index",
 *   path = "/my/custom/search",
