          Issue Type: Improvement
            Reporter: Liu Shaohui

Kylin has many inner meta data and outer dependencies. There may be no inconsistent for bugs
or failures. It's better to have a a health check job to find these inconsistent issues in
advance。

The inconsistent issues we found in our clusters are followings
 * {color:#808080}the cubeid data not exist for cube merging
{color}
 * {color:#808080}hbase table not exist or online for a segment{color}
 * {color:#808080}there are holes in cube segments(The build of some days failed, but user
not found it){color}
 * {color:#808080}Too many segment(hbase tables){color}
 * {color:#808080}metadata of stale segment  left in cube{color}
 * {color:#808080}Some cubes have not be updated/built for a long time{color}
 * {color:#808080}Some  important parameters are no set in cube desc{color}
 * {color:#808080}...{color}
