Support XML marshaling of Configuration instances
-------------------------------------------------

                 Key: ISPN-948
                 URL: https://issues.jboss.org/browse/ISPN-948
             Project: Infinispan
          Issue Type: Feature Request
          Components: Configuration
    Affects Versions: 4.2.1.CR3
            Reporter: Jürgen Kellerer
            Assignee: Manik Surtani
             Fix For: 4.2.1.FINAL, 5.0.0.Final


Infinispan supports a very flexible way of configuring caches using multiple levels of inheritance. 
While this is really nice, it is sometimes not easy to understand how exactly a particular cache was configured. 
(E.g. JPA is just one example where a cache configuration can be adjusted in several ways).

JMX or debuggers help but may not always be available.

What about allowing to convert a configuration instance back to XML to give a quick overview of the really applied settings. _(Optionally it might also be a nice little feature to implement a "toXmlString();" method or override the default and also make this available through JMX)_

JAXB annotations are already present on all configurable options but a couple getters and a @XmlRootElement annotation is missing that would allow to convert an existing instance back to XML. The effort in doing this should be rather low.

---
This feature request may also fit with #ISPN-791 as it would allow to transfer cache configs using XML.
