IMPALA-6479: Update DESCRIBE to respect column privileges

Modified the Frontend to filter columns from the DESCRIBE
statement.  Additionally, if a user has select on at least
one column, they can run DESCRIBE and see most metadata.
If they do not have full table access, they will not see
location or view query metadata.

Testing:
Added tests to validate users that have one or more column
access can run describe and that the output is filtered
accordingly.
