Add cfn-lint to CloudFormation SDK

[bildungsroman]

Is this feature request related to a new rule or cfn-lint capabilities?

New capability

Describe the feature you'd like to request

Currently, the CloudFormation SDK has a ValidateTemplateCommand that is ...pretty useless as a validator. It would be amazing to have that command run cfn-lint as return the results instead.

Describe the solution you'd like

Have the ValidateTemplateCommand return the results of running cfn-lint on a template.

Also, being that AWS SDK does come in a Python flavor, the Python version could pick up cfn-lint libs directly instead of needing to run the commandline binary like I assume non-Python SDKs would
