rds_instance_facts module
Create rds_instance_facts module using boto3. Create common rds.py module_util library to be used by rds_instance_facts and future RDS modules. rds_instance_facts: use latest AWS helper methods * Use `module.client` with `retry` to create AWS connection * Return tags, using AWSRetry helper to backoff * Use paginator to describe DB instances * Further improve exception handling * Fix RETURN documentation update version_added Co-authored-by: Michael De La Rue <jababubic.margoteen@spamgourmet.com>
