* @param array $options Array of options. Possible keys are:
* - `cache` - Can either be `true`, to enable caching using the config in View::$elementCache. Or an array
* If an array, the following keys can be used:
* - `config` - Used to store the cached element in a custom cache configuration.
* - `key` - Used to define the key used in the Cache::write(). It will be prefixed with `element_`
* - `plugin` - Load an element from a specific plugin.
