* Enabling pylint rule in hive.py:
- `no-name-in-module` for pyhive in several places
- `line-too-long` and adding new lines
- `unused-import` is not invalid anymore

* Enabled `line-too-long` in `kylin.py`. Added variable for too long string.

* Enabled `unused_import` in `base.py` from db_engine_specs module.

* Enabled `unused_import` in `bigquery.py` from db_engine_specs module.
