Question: How can I get result types for a Hive query?

`.description` gives:

```
[(u'my_schema.col_one', u'BIGINT_TYPE', None, None, None, None, True),
(u'my_schema.col_two', u'DATE_TYPE', None, None, None, None, True),
(u'my_schema.col_three',
u'BIGINT_TYPE',
None,
None,
None,
None,
True)]
```

So the second field gives the types, but I would really like to be able to get at column types I can use in DDL statements. In this case, BIGINT, DATE, and BIGINT.

**What's the best way to do this?**

I see two options:
1. String manipulation. Strip `_TYPE` off.
2. Add it to `DBAPITypeObject` by looking it up in `TCLIService.constants.TYPE_NAMES`:

```
for type_id in constants.PRIMITIVE_TYPES:
name = ttypes.TTypeId._VALUES_TO_NAMES[type_id]
setattr(sys.modules[__name__], name, DBAPITypeObject([name], constants.TYPE_NAMES[type_id]))
```

Then add `__str__` to `DBAPITypeObject` which returns a valid column name for use in DDL statements.
