/**
* Retrieves plugin installer pages from the WordPress.org 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
* overriding the filters.
*
* 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 `$action` type.
*
* Supported arguments per action:
*
* | Argument Name | query_plugins | plugin_information | hot_tags | hot_categories |
* | -------------------- | :-----------: | :----------------: | :------: | :------------: |
* | `$slug` | No | Yes | No | No |
* | `$per_page` | Yes | No | No | No |
* | `$page` | Yes | No | No | No |

* | `$search` | Yes | No | No | No |

* | `$author` | Yes | No | No | No |
* | `$user` | Yes | No | No | No |
* | `$browse` | Yes | No | No | No |
* | `$locale` | Yes | Yes | No | No |
* | `$installed_plugins` | Yes | No | No | No |
* | `$is_ssl` | Yes | Yes | No | No |
* | `$fields` | Yes | Yes | No | No |
