##### SUMMARY
While `ansible-config dump` is a very useful tool for determining the configuration used by Ansible at runtime, it does have a major flaw: its output is not machine parseable.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
ansible-config

##### ADDITIONAL INFORMATION
ansible-config should have an option to dump config in a machine parseable format like JSON or YAML, so it can be consumed by other tools.
