  10   * Retrieves plugin installer pages from the WordPress.org Plugins API.
  11   *
  12   * It is possible for a plugin to override the Plugin API result with three
  13   * filters. Assume this is for plugins, which can extend on the Plugin Info to
  14   * offer more choices. This is very powerful and must be used with care when
  15   * overriding the filters.
  16   *
  17   * The first filter, {@see 'plugins_api_args'}, is for the args and gives the action
  18   * as the second parameter. The hook for {@see 'plugins_api_args'} must ensure that
  19   * an object is returned.
  20   *
  21   * The second filter, {@see 'plugins_api'}, allows a plugin to override the WordPress.org
  22   * Plugin Installation API entirely. If `$action` is 'query_plugins' or 'plugin_information',
  23   * an object MUST be passed. If `$action` is 'hot_tags', an array MUST be passed.
  24   *
  25   * Finally, the third filter, {@see 'plugins_api_result'}, makes it possible to filter the
  26   * response object or array, depending on the `$action` type.
  27   *
  28   * Supported arguments per action:
  29   *
  30   * | Argument Name        | query_plugins | plugin_information | hot_tags |
  31   * | -------------------- | :-----------: | :----------------: | :------: |
  32   * | `$slug`              | No            |  Yes               | No       |

  34   * | `$page`              | Yes           |  No                | No       |
  35   * | `$number`            | No            |  No                | Yes      |
  36   * | `$search`            | Yes           |  No                | No       |

  40   * | `$browse`            | Yes           |  No                | No       |
  41   * | `$locale`            | Yes           |  Yes               | No       |
