* Remove duplicate package import
Package "k8s.io/api/core/v1" was imported twice with names "v1"
and "corev1".
* Mount GCP secret only when accessing Google storage
The Tensorboard controller used to create pods (running the Tensorboard
server) that would always mount user-gcp-sa secret, regardless of the
logs storage being a Google cloud bucket or not. This would lead to pods
never starting properly in the case of using other cloud services (or
PVCs) as log storages, if the user-gcp-sa secret didn't exist on the
cluster.
In order for the Tensorboard server pods to run properly, user-gcp-sa
secret is now mounted only when Google cloud buckets are used as log
storages.
Fixeskubeflow/kubeflow#5065
* Fix docker builds of notebook and tensorboard controller
* The notebook-controllers and tensorboard-controllers now depend on
the go package components/common
* We need to rewrite the Dockerfiles so that the context is now
${KUBEfLOW_REPO}/common
* so that components/common can be included in the context and copied
to the Dockerfile
* Create skaffold configs to make it easier to do remote builds with Kaniko
* The skaffold configs are currently written assuming the kubeflow-ci cluster
is used to build the images. This could be generalized in the future.
* Remove the code to build the notebook-controller with GCB; we can just
use skaffold and kaniko to do efficient remote builds.
* Related to #4582 - Jupyter image doesn't build.
* Fix docker build rule.
* The jupyter docker image isn't building because it now depends on code
in components/common
* To make this work we need to configure it as a multi module package
and modify go.mod to redirect to a local path.
