Hi community,

Currently carbon supports alter table rename, add column, drop column and
change datatype command.

I want to propose alter table column rename feature in carbondata.
If user has an old table and he wants to change some column names as those
columns does not meet his current business scenarios. So we can support
this feature.

Please give your inputs to this so that i can start with the design and the
implementation.

DDL used for this is same as existing datatype change command DDL
ALTER TABLE table_name CHANGE [COLUMN] col_old_name col_new_name column_type;
