Description

Initially suggested by Hoss at https://issues.apache.org/jira/browse/SOLR-350?focusedCommentId=12562834#action_12562834 and taken forward by Henri in SOLR-646

1. Allows users to define global as well as core-specific properties in solr.xml which can be used in solrconfig.xml and schema.xml

   <solr persistent="false">
   
     <property name="var" value="value" />
   
     <cores adminPath="/admin/cores">
       <core name="core0" instanceDir="core0">
         <property name="var" value="value" />
       </core>
       <core name="core1" instanceDir="core1" />
     </cores>
   </solr>
   

2. The following core-specific properties will be added automatically:
   • solr.core.instanceDir
   • solr.core.name
   • solr.core.configName
   • solr.core.schemaName
3. The variable substitution will be done in this fall-back order – core-specific, implicit, global, system properties.
4. The properties defined in solr.xml should also be persisted back as is (without evaluation).
