Solving CORS problem on embedding Pentaho CDE dashboard in web application

Cross-Origin Resource Sharing (CORS) is a W3C spec that allows cross-domain communication from the browser. By building on top of the XMLHttpRequest object, CORS allows developers to work with the same idioms as same-domain requests.

Enable Cross Origin Resource Sharing (CORS) in the Community Dashboard Framework (CDF), Community Dashboard Editor (CDE), and Community Data Access (CDA). While you need CDE to embed the dashboard, you will access it from a different server other than the Pentaho Server, so CORS must be enabled in CDF, CDE and CDA. Open the following CDF, CDE, and CDA settings.xml files in a text editor:

For CDF: server/pentaho-server/pentaho-solutions/system/pentaho-cdf/settings.xml.
For CDE: server/pentaho-server/pentaho-solutions/system/pentaho-cdf-dd/settings.xml.
For CDA: server/pentaho-server/pentaho-solutions/system/cda/settings.xml.

These scripts let you run Redis in cluster mode (only for testing/dev purpose), without using the redis-trib script (written in Ruby! who wants it!?). The create-cluster has been modified to assign cluster slots after creation.
