[CARBONDATA-839] Fixed issue with meta lock not getting deleted for rename 
table

The following things are fixed in this patch:

1. Meta lock location has been changed from "tmp" to table store location.
2. The meta lock file was not being delete when the lock was released in 
case of table rename because the  path stored in the lock would not be updated 
along with the table rename. To fix this, a new method to manually delete the 
lock file has been added in AbstractCarbonLock.

You can merge this pull request into a Git repository by running:

$ git pull https://github.com/kunal642/incubator-carbondata CARBONDATA-839

Alternatively you can review and apply these changes as the patch at:

Now no-dictionary column use LV(length-value) encoding. It isn't the best 
choice for numeric type column.
