add dependabot config script

[davidspek]

Inspired by kubeflow/pipelines#4682 I created a script that will create a config file for depandabot so that it knows what directories to scan. It will scan the repository for files named *ockerfile*, package*.json, *requirements.txt, go.* and Gemfile*. It is setup for dockerfiles, npm packages, pip, ruby and gomod dependencies at the moment. It is trivial to further customize what folders are selected if further customization is needed. It also parses the closest OWNERS file for a given dependency listing file, and assigns the relevant approvers and adds the relevant reviewers to the PRs it creates.

This is a sibling PR to kubeflow/pipelines#5015, kubeflow/kubeflow#5542, kserve/kserve#1309, kubeflow/arena#403, kubeflow/testing#855, kubeflow/fairing#550, kubeflow/kfp-tekton#432, kubeflow/katib#1420, kubeflow/training-operator#1224, kubeflow/kfp-tekton-backend#28, kubeflow/mpi-operator#319, kubeflow/pytorch-operator#315, kubeflow/metadata#255, kubeflow/xgboost-operator#107, kubeflow/fate-operator#26, kubeflow/mxnet-operator#87, kubeflow/website#2459, kubeflow/kfctl#479, kubeflow/examples#843, kubeflow/code-intelligence#198, GoogleCloudPlatform/kubeflow-distribution#192 and kubeflow/common#107.

As it stands now, there will be about 11 PRs that will be created with this configuration.

@terrytangyuan I wasn't able to assign the owner of the repo @kramachandran as he isn't a member of Kubeflow. Who should be assigned to approve this?

[davidspek]

I am holding the PR to have some control over when it gets merged so that the optional test infra doesn't get overloaded if all the repo's were to merge this at the same time.
/hold

I think we don't need this for kubeflow/blog, do we?

[davidspek]

@Bobgy does look like there are things that need to be kept up to date.
