Add cache_response option to completable form fields

Browse source 
When `cache_response` is set to `false` for completable fields the returned options will not be
cached on the client side. The default is `true`.

Clearing the cache is needed when the completable response depends on a different option of the Agent.

Usage Example:

```
form_configurable :models, roles: :completable, cache_response: false
```

* Disable the completion callback when `select2` is opened programmatically to avoid an infinite loop
* Moved the completion ajax call from `select2-open` to `select2-opening` to clear the cached results before
 `completableDefaultOptions` is called (shows the "Loading ..." message instead of the previous results)
