Deprecate MXJob from Training Operator

[andreyvelich]

Unfortunately, Apache MXNet project has been archived: https://attic.apache.org/projects/mxnet.html Original GitHub repo: https://github.com/apache/mxnet.

This issue is to track plan for Training Operator to remove MXJob support. We are going to deprecate MXJob with the two stages:

• [x] In Training Operator 1.8 release we will notify users that MXJob is deprecated and it will be removed in the next release version.

  • [x] We need to update the Kubeflow website
  • [x] We need to add a deprecation notice on the MXJob APIs.

• [ ] In Training Operator 1.9 release we will remove support for MXJob.

@terrytangyuan @tenzen-y @kubeflow/wg-training-leads Any other places where we should add deprecation notice ?

@kubeflow/wg-training-leads If we can pin this issue, it would be great.

@tariq-hasan Thank you for removing MXNet from Training Operator. Please can you also create PR to remove content from the website: https://www.kubeflow.org/docs/components/training/user-guides/mxnet/ ?
