* Retrieve plugin installer pages from WordPress Plugins API.

* It is possible for a plugin to override the Plugin API result with three
* filters. Assume this is for plugins, which can extend on the Plugin Info to
* offer more choices. This is very powerful and must be used with care, when
* overridding the filters.
*
* The first filter, 'plugins_api_args', is for the args and gives the action as
* the second parameter. The hook for 'plugins_api_args' must ensure that an
* object is returned.
*
* The second filter, 'plugins_api', is the result that would be returned.
*
* @param string $action
* @param array|object $args Optional. Arguments to serialize for the Plugin Info API.
