New UI section for API Tokens

We are glad to introduce a new UI for Storage Api Tokens that can be now found under the Users & Settings section. We will be removing the old one found under Storage section. The new UI covers the same functionality as the old one.

As a security measure, the token itself will not be shown anymore, only once after its creation. The only way to see an existing token in the UI is to send it via email (temporary link to token is sent) or refresh it and get a new token string. On the backend, the token can still be seen in the response from the tokens list api call but will be removed in the near future.
