Changes
 * Changed the type of the SolrInfoMBeans to the key specified in registry. Previously, I had used the SolrInfoMBean class's simple name which lead to duplicate registration of LRUCache (which is used as filterCache, queryResultCache and documentCache).
 * Fixed the parent name of the MBeans to solr (if using single cores). With multicores, the parent name is solr/core-name
 * Throws an exception if no server is found with the given agentId
 * Removed code I had added for debugging

Also, I've added <jmx /> in the example solrconfig.xml to turn on JMX by default.

> This patch adds JMX capability to get statistics from all the SolrInfoMBean.
> The implementation is done such a way to minimize code changes. 
> In SolrInfoRegistry, I have overloaded Map's  put and remove methods to register and unregister SolrInfoMBean in MBeanServer. 
> Later on, I am planning to use register and unregister methods in SolrInfoRegistry and removing getRegistry() method (Hiding the map instance to other classes)
