Several enhancements to LiveOak Console

- More real data to the dashboard (only metrics for admin are mocked, 0 is shown when no metrics available). Showing actual app key, security realm, storage resources and push config;
- Input validation by RegExp (IP, Host, Port, URL);
- Enable Save button only when forms are valid;
- Directive to automatically add http:// prefix when inputing an url field;
- UPS Console link to application added in push config;
