* Service discovery API endpoint: simple, read-only, unauthenticated access to a list DNS names of services. Needed for frameworks that need a list of hosts for configuration, can be used by scripts in the images.
* Add `start -s` option to the Zoe commandline client to have it wait for execution termination and stream the log meanwhile.
* Add the `workspace-deployment-path` option in the configuration file. It should be used when the workspace path should be build not with the deployment name, but with something else.
* All errors generated by docker while creating containers are now considered as fatal, except the "not enough free resource" one. When a fatal error is generated, Zoe will not try to start the execution again.
* Error messages generated by Docker are now exposed to the user
