ConfigurationExtensions is used to hold:
- custom configuration parameters of a component,
- and, configuration parameter of interceptor,
- and, configuration parameter of service units.
ConfigurationExtensions provides a mechanism to be able to resolved configuration parameter value with a place holder. This is needed mainly for service unit that are not customizable on installation (The only way is to used a property file set at component level in which place holder value are defined).
A new class should be introduced to represent only service unit configuration parameter.
