CarbonLock Exception refractor

[ZhuWilliam]

Carbondata will try to lock table/column/dict when loading data. However ,for now ,it silences the exception and just return false,then tells the user "Table is locked for updation. Please try after some time" which  makes people confused. There are a lot of reasons which can make locking  fail. Maybe we should refractor here to give
users more specific error .

I agree to refactor code to give detail information.

Yes, that can be more meaningful, detailing the exception type. Any related
changes are welcome.

Hi William

+1 for improving CarbonLock Exception.

Do you have any proposed solution for this improvement, and can you raise one PR for it.
