Title: LevelDB Cache Store Sample XML Configuration (Library Mode)

Describe the issue:
<namedCache name="vehicleCache">
      <loaders passivation="false" 
                   shared="true" 
                   preload="true">
        <leveldbStore location="/tmp/leveldb/data"
                            expiredLocation="/tmp/leveldb/expired" />
      </loaders>
</namedCache>

Suggestions for improvement:
 <namedCache name="vehicleCache">
      <persistence passivation="false">
         <leveldbStore location="/path/to/leveldb/data" expiredLocation="/path/to/expired/data shared="true" preload="true"/>
      </persistence>
   </namedCache>
