Replacement of master/slave by primary/secondary. The changes related to producing new configuration files should not affect WildFly, but I do think it will be better to align both projects now; this change will affect some startup up scripts, e.g. service.bat, and init.d configurations.

Included tasks:

• Changes to produce new host-primary.xml / host-secondary.xml.
• Use "primary" as the default hostname for the primary host controller.
• Review and fix affected tests.
• Changes for init.d service configuration. We have to use conversion branches to ensure the changes will go to the product branch.
• Change Web Console Error pages replacing occurrences. We have to use conversion branches to ensure the changes will go to the product.
• Rename Galleon pack feature groups and related files
