- Add DebugAddress helper to validate and parse the (legacy) debug-port and debug-address. Later has precedence.
 - Streamline the CommandBuilder implementation ensuring that the Java and Docker specific code runs inside the command builder and is not spilled out to the AbstractLocalDeployerSupport or AppLocalDeployer.
 - Update affected tests (also migrate those to JUnit5).
 - Improve code cohesion and remove death code.

 - Change GUID from 'port' to 'deployerId-index'.
 - Allow the Docker and Java command builder use different port range. Needed to allow in-container Skipper to operate with both maven and docker resources.

 - use <deploymentId>-<instance index> as container name to allow support for multiple app instances

- if the DOCKER_CONTAINER_NAME_KEY is not explicitly set use the dockerId for container name.
 - By default remove the docker containers on exist.
 - Add a docker.deleteContainerOnExit property to control the removal of stopped containers. Set to true by default.

- When getting logs for stream and task apps we used
  to just read stderr if it had some content which
  is a bit problematic as stderr may have some content
  which is not a real error.
- This i.e. happens with JAVA_TOOL_OPTIONS env variable.
- Now simply getting both.
- Fixes #193

- Fixes #194

* Add startup/health probes for stream apps

- Adding an optional startup probe which simply checks
  2xx return code to mark when new app goes from deploying
  to deployed.
- Adding an optional health probe which simply checks
  2xx return code to mark when running app is marked either
  deployed or failed.
- Essentially adding `startup-probe.path` and `health-probe.path`
  with very minimal functionality but allows to easily add
  more features in future if needed.
- Together these allow to do failed stream update locally as
  previously it has only been possible in cf/k8s.
- Fixes #189

* Add javadocs

- Move away from BeanUtils.copyProperties to
  manually copy LocalDeployerProperties as
  its nested structure.
- Fixes #190

- Fix changed OutputCapture vs. OutputCaptureRule in boot
- Fixes #184

 - The spring.cloud.deployer.local.docker.network allows setting the container network. When provided it adds --network <scdf network name> to the DockerCommandBuilder to ensure that the deployed app containers are connected to the network created by the docker-compose (note that the -p project-name). For default docker-compose installations set the dockerNetwork to spring-cloud-dataflow-server_default
 - Set the deployment-id as docker container name of the deployed app.
 - Change the AppInstance URL to <deployement-id>:<app-port> (the URL uses the local/skipper IP otherwise).
 - Backward compatible with not docker compose local installations
