SOLR-13822: Isolated Classloading from packages (#957) 

SOLR-13822: A Package management system with the following features. A packages.json in ZK to store
  the configuration, APIs to read/edit them and isolated classloaders to load the classes from
  those packages if the 'class' attribute is prefixed with `<package-name>:`
