[Another `AWS::Events::Rule.ScheduleExpression` request](https://github.com/aws-cloudformation/cfn-python-lint/issues/1351) [Another `AWS::Events::Rule.ScheduleExpression` request](https://github.com/aws-cloudformation/cfn-python-lint/issues/1723) **[existing `AWS::Events::Rule.ScheduleExpression` rule](https://github.com/aws-cloudformation/cfn-python-lint/blob/master/src/cfnlint/rules/resources/events/RuleScheduleExpression.py)**

process of writing [`src/cfnlint/data/ExtendedSpecs/all/`](https://github.com/aws-cloudformation/cfn-python-lint/tree/master/src/cfnlint/data/ExtendedSpecs/all/) and generating [`src/cfnlint/data/CloudSpecs/`](https://github.com/aws-cloudformation/cfn-python-lint/tree/master/src/cfnlint/data/CloudSpecs) described here: https://github.com/aws-cloudformation/cfn-python-lint/issues/903#issuecomment-595356853

I'd like to start leveraging [botocore enums](https://github.com/boto/botocore/blob/2300e3a87e2835c93d832ee9c8ec7433cfa7fe18/botocore/data/dms/2016-01-01/service-2.json#L2005-L2013) instead of maintaining all the AllowedValues in the Linter source code itself especially since that was the most commonly maintained [concise constraint format](https://github.com/aws-cloudformation/cfn-python-lint/issues/903#issuecomment-595356853)...

I really like this rule idea and think it's generalizable beyond this specific resource type: https://github.com/aws-cloudformation/cfn-lint/pull/3023

At least for public resource types, we also have plans to improve the modeling of the property types themselves, which should help for those
