Isolate Bootstrap Config from Application Config

The bootstrap config properties should be isolated from the application configuration. This was done by moving the bootstrap properties under spring.cloud.config.

In order to upgrade from v1 to v2, you just need to prepend spring.cloud.config to all of your bootstrap.yml properties. Please refer to the updated README for full details.

Profile-Based Config File Names

This release adds the capability to define your application configuration using separate yaml files for each profile you use, instead of keeping all profiles in the same yaml file.

Initial Release

This is the initial release of spring-cloud-config!
