### What changes were proposed in this pull request?
Added the copy translation for grouping UDF keys without this the keys in
the grouping UDF will not be matching with the keys mentioned in the GROUP BY
clause and throws `java.lang.RuntimeException: Expression in GROUPING function
not present in GROUP BY` when parsing the view definition while selecting data
from view.
When view is created, the view definition is stored by adding the column
names along with table name and table name along with schema name(for example,
col1 will be replaced with `tbl`.`col1`) but the same is not happening for
grouping UDF keys due to this when the select query run on this view throwing
exception.
