   Adds `RedshiftStatementHook` and `RedshiftOperator`, which allow Airflow 
users to execute Redshift operations.
   
   `RedshiftStatementHook` is supported by the `redshift_connector` database 
driver which supports authenticating via IAM or Identity Provider. Integration 
with `sqlalchemy` is supported via `sqlalchemy-redshift`. 
   
   Unit tests have been added to:
   - Test Hook -- ensuring connection parameters flow through to 
`redshift_connector` as expected
   - Test Operator -- ensuring statements flow through to 
`redshift_connector.execute` method as expected
   
   Docs have been added to:
   - explain how to build a connection
   - provide an example DAG with create/insert/select statements
   - provide reference to `redshift_connector` docs for details about supported 
connection options
   
   
   ### Use case / motivation
   Please see #16355
   tl;dr: Provides support for IAM & Identity provider authentication as well 
as Redshift specific datatype support (e.g. GEOMETRY, SUPER, etc.).
