Hello,
Using the ImpalaHook with kerberos ([`"auth_mechanism":
"GSSAPI"`](https://github.com/cloudera/impyla/blob/master/impala/dbapi.py#L74))
fails with the following error:
```python

'impala_conn' for task execution.

### Solution
The [kerberos](https://pypi.org/project/kerberos/) module, an optional
dependency of impyala, is not bundled with Airflow. (Only requests-kerberos for
hdfs and pykerberos come default with Airflow, if I'm not mistaken)
**This PR add `kerberos` as dependency**. Fixing the above error.
### About licences
The package is under Apache 2.0 license (see [github
repo](https://github.com/apple/ccs-pykerberos/blob/master/LICENSE.txt), and
[pypi](https://pypi.org/project/kerberos/)).
