kie-server: add tomcat8x and wildfly8x profiles + tweak cargo configuration

 * using jboss-deployment-structure.xml and disabling CDI as Wildfly 8.x
   tries to start the CDI service and instantiate beans that should be
   actually managed by Guice. As of now CDI is not required for Kie Server

 * added download.url property for each container so the default can be
   overriden and the container does not have to be downloaded every time
   from remote location

 * using cargo deafult location for downloads and installs as there
   is no need to use the custom ones (this was just leftover from
   copy-pasting the config)
Yap, now I got it, sorry, brain is slow today... :) I also agree then that it might be best to use the config option you mentioned then. Thanks!
