    KAFKA-1614: Partition log directory name and segments information exposed via JMX

    This is an updated version of https://issues.apache.org/jira/browse/KAFKA-1614 patch which was made for 0.8.1.1 version. 
    
    It makes partition log directory and single segments information exposed via JMX. This is useful to:
    * monitor disks usage in a cluster and on single broker;
    * calculate disk space taken by different topics;
    * estimate space to be freed when segments are expired.
    
    Yahoo's Kafka Manager uses it to show information about topics and partitions sizes:
    
    ![topics](https://cloud.githubusercontent.com/assets/1021271/14336342/aa3a197a-fc17-11e5-9ae8-7a4a8bf32562.png)
    ![partitions](https://cloud.githubusercontent.com/assets/1021271/14336348/b38e2354-fc17-11e5-930d-9b36c7aae1e8.png)
    
    Our internal tool uses it to show how segments sizes were changing over time:
