Define a v0.8 release

* Update applications.yaml with a v0.8 release.

* The purpose of this PR is to check that just by defining the appropriate
  release we can begin building images from release branches and updating
  the release branch of kubeflow/manifests

* Related to kubeflow#450 - Continuous delivery of Kubeflow applications
