V1Alpha2 Update

• The PredictorSpec componentSpec is now componentSpecs and takes a list of PodTemplateSpecs allowing you to split your runtime graph into separate Kubernetes Deployments as needed. See the new proto definiton. To update existing resources:
  • Change "apiVersion": "machinelearning.seldon.io/v1alpha1" to "apiVersion": "machinelearning.seldon.io/v1alpha2"
  • Change componentSpec -> componentSpecs and enclose the existing PodTemplateSpec in a single element list

For example change:
