* Retrieves plugin installer pages from the WordPress.org Plugins API.

 * offer more choices. This is very powerful and must be used with care when

 * The first filter, {@see 'plugins_api_args'}, is for the args and gives the action

 * as the second parameter. The hook for {@see 'plugins_api_args'} must ensure that

 * an object is returned.

 *

 * The second filter, {@see 'plugins_api'}, allows a plugin to override the WordPress.org

 * Plugin Installation API entirely. If `$action` is 'query_plugins' or 'plugin_information',

 * an object MUST be passed. If `$action` is 'hot_tags' or 'hot_categories', an array MUST

 * be passed.

 *

 * Finally, the third filter, {@see 'plugins_api_result'}, makes it possible to filter the

 * response object or array, depending on the `$action` type.

 *

 * Supported arguments per action:

 * | Argument Name        | query_plugins | plugin_information | hot_tags | hot_categories |
