New module: Add module to collect facts for Amazon Redshift Cluster (cloud/amazon/redshift_facts) (#22615)

* New module redshift_facts

Gather facts about aws Redshift cluster(s).

* Fix she-bang, PEP8 violations, and ansible metadata.

* Bump version_added to "2.4"

* Fix some typos and add supporting check mode

* Fix type of RETURN fields

Fix type of RETURN fields number_of_nodes and
automated_snapshot_retention_period from integer to int.

* Add traceback information to fail_json()
