* Add build and test presubmit jobs for Pytorch nmist example
Keep postsubmit jobs as original release job to push images to examples registry
* Refactor all jobs like mnist and GIS, will drop using release jobs
* Implement test scripts and Ksonnet artifacts from mnist example to enable E2E tests
* Remove release components as they are no longer used
* Refactor YAML manifests as Ksonnet components
* Update documentation to submit training jobs from Ksonnet
* Updated to point to correct component and refactor to PytorchJob
* Add seldon image build
Add train CPU and GPU in jsonnet to build workflow
Add Dockerfile.ksonnet and entrypoint
* Commented out calls to tf-util until
https://github.com/kubeflow/pytorch-operator/issues/108 is implemented
* Refactor to PytorchJob
* Add seldon image build
Add train CPU and GPU in jsonnet to build workflow
Add Dockerfile.ksonnet and entrypoint
* Refactor to PytorchJob
* Rename workflow to avoid dns issue with "_"
* Add TODO note to convert to GRPC
* Rename workflow to avoid dns issue with "_"
* Rename workflow to avoid dns issue with "_"
* Fix path to build Seldon image in Makefile
* Fix tabs in Makefile
* Fix tabs in Makefile
* Fix rule in Makefile
* Add sleep in Makefile to wait for docker ps
* Change node worker image to have docker
* Remove seldon image step from Makefile
Add steps to wrap model with Seldon
Add boolean flag to build Seldon steps
* Add step id build- in jsonnet
* Skip pull step for Seldon
* Fix wait for in Seldon build
* Fix lint errors
* Set useimagecache to false first time the pipeline is executed to avoid error
* Set contextDir as absolute path for Seldon step
* Remove unnecessary argument and Dockerfile in Seldon step
* Add absolute path for build in Seldon steps
* Include absolute path inside jsonnet hardcoded to GCB /workspace/
Remove setting rootDir from Makefile
* Update images with new naming from E2E tests
* Change test-worker image version
* Update images with new naming from E2E tests
* Set useimagecache to true now that we have first images built
* Fix cachelist in Seldon build
* Fix cachelist in Seldon build
* Leverage tf-operator test framework for test_runner
As per https://github.com/kubeflow/pytorch-operator/issues/108
* Consolidate testing imports
Rename testing package as https://github.com/kubeflow/tf-operator/pull/945
Added correct path to import test framework from tf-operator
* Add test framework in PYTHONPATH in build_template
* Remove old release jobs to build images
* Update stepimage to same as GIS example
* Bump up supported Pytorch operator versions from v1alpha2/v1beta1 to v1beta1/v1beta2 to support Kubeflow 0.5
- Refactor training manifests from v1alpha2 to v1beta2
- Update documents
* Update KF cluster version to latest to run tests
* Update KF cluster zone
* Add pylint exception while importing test_runner class from tf-operator
* Pass dummy tests to train, deploy and predict
Remove no longer used test_data and conftest
* Pass dummy tests to train, deploy and predict
Remove no longer used test_data and conftest
