Deprecation: Javascript API, all.js, must be loaded from Connect CDN

This is a companion notice to the deprecation of the xdm_e and associated context parameters I posted previously. Thank you for your feedback there. This notice highlights the change in the nature of how apps should load all.js.

From 01 Feb 2020, all apps must load the Connect Javascript API, all.js, from the connect-cdn. From this date the all.js file will no longer be available through the host product (Jira or Confluence) base URL.
