The implementation is based on the API, that define in commitlog.json
After this patch, it will be possible to connect with jconsole and see
the CommitLogMetrics.

This adds two of the supported CommitLog method, the
getActiveSegmentNames and the getArchivingSegmentNames.
The API for both returns full path, so the JMX API takes the file name
from the path and remove duplicates.
