Rely on spring-cloud-deployer autoconfig

- Deployer core/local uses 2.0.0.BUILD-SNAPSHOT
- Use pring-cloud-deployer-dependencies bom
- Remove ResourceLoadingAutoConfiguration as that is now in
  deployer itself with a way to configure loaders.
- spring-cloud-task-core now depends on spring-cloud-deployer-autoconfigure.
- Rest of deployer modules like support/maven are still defined in deps
  as those are optional in spring-cloud-deployer-autoconfigure.
