Description

Currently each pre-req check must add an entry in the CheckDescription enum. This limits the ability for third party stacks and extensions to provide their own pre-req checks.

The CheckDescription enum should be rewritten as a class and each pre-req check class should create an instance of it. This will allow stacks and extensions to include their own pre-req checks in separate jar files without requiring changes to ambari-server java code.
