Dennis Benkert 28d0a173db [aws] add limit on number of CloudFormation stack events fetched by cloudformation module (#41840)
* Add a module parameter to configure the max fetched AWS CFN stack events
* Add version documentation for new configuration option
* Increase default in order to make sure that enough are fetched by default. This align roughly with the limit of manageable resources in CloudFormation.
