> 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.
