Instead of using Map everywhere it's neater to use a strongly typed

object. This reuses JGitEnvironmentRepository, since it shares
most of the same properties. The format of the repos config
changes - now it is a Map not a List and the key is used as a "name"
to provide a default pattern and a location in the basedir.

Example config:

    spring:
      application:
        name: configserver
      cloud:
        config:
          server:
            git:
              uri: https://github.com/spring-cloud-samples/config-repo
              repos:
                iceycake: https://github.com/iceycake/config-repo
                project1:
                  patterns: project1-*,*-project1
                  uri: https://github.com/spring-cloud-samples/config-repo-1
