[AIRFLOW-509][AIRFLOW-1] Create operator to delete tables in BigQuery

We have a use case to delete BigQuery tables and views. This patch
adds a delete operator that allows us to do so.

Closes #1798 from illop/BigQueryDeleteOperator

> Airflow currently has several operators for BigQuery, but none of them are able to delete tables. The request is to create a new operator that will be able to do this.
> An important application of this is to help refresh views for which the schema of the underlying tables is subject to change. BigQuery has no functionality to refresh the schema of a view, so if the underlying table changes the schema will not have the new data and things like auto-completion will not work in the UI. By deleting a view and re-creating it, we can force a schema refresh.
