Form.io definitions cache update for releases

[andrewsignori-aot]

Currently, the form.io definitions downloaded by the Vue/Web application are kept in the browser session storage. When a new deployment happens it will not be refreshed automatically, it only happens when the browser is closed.

• When a new deployment happens we should force the web application to download again the form.io definition. One suggestion would be to make available the version in the Vue application and use it as part of the storage key (source reference), in this way, when a new application is deployed all the form.io storage cache will be "invalidated".
