Wrong priority order of multiple configs in bootstrap mode

[woshikid]

When using Spring Cloud Config, the priority order of multiple configs is as follow: (both import mode and bootstrap mode)

1. configserver:foo-dev.yml
2. configserver:application-dev.yml
3. configserver:foo.yml
4. configserver:application.yml

and Spring Cloud Zookeeper Config take a similar order when using spring.config.import

1. zookeeper:config/foo,dev
2. zookeeper:config/application,dev
3. zookeeper:config/foo
4. zookeeper:config/application

BUT when using bootstrap mode, the client load configs in a strange priority order:

1. zookeeper:config/foo,dev
2. zookeeper:config/foo
3. zookeeper:config/application,dev
4. zookeeper:config/application

this can be confirmed by using /actuator/env api.

I've made a PR #303 on this.
