[ApacheDS] Adding my own stored procedure engine

[Stefan Zoerner]

Hi all!

I tried to create my very own StoredProcEngine, and it seems to be 
possible and easy. But there is a place where I see some potential for 
improvement.

It is not possible to add a new StoredProcEngineConfig to the 
StoredProcedureExtendedOperationHandler. It would be nice to have it 
configurable with Spring, because it would make it possible to add a new 
engine without code change (Open Closed Principle).

I would like to change this. Default list of StoredProcEngineConfigs  is 
the { JavaStoredProcEngineConfig }, but another constructor allows to 
set a list of others as well.

What do you think?
