Is your feature request related to a problem? Please describe.
I would like to fetch configuration from AppConfig on application start up. This way I can keep my whole configuration away from my code and keep it in a same place as configuration for other applications.

Describe the solution you'd like
For this I would like to use Spring.config.import.
Example:
spring.config.import: aws-appconfig:applicationId___configurationId___environment
We can use another char for splitting ___ 3 * _ is just an example.

Describe alternatives you've considered
Currently I would have to write my own implementation
