Delete Suggestion deployment after Experiment is finished

[andreyvelich]

/kind feature

Right now, when user creates Experiment, Suggestion deployment is always running. Even after Experiment is finished.
We should add Flag in the API if user wants to delete Suggestion deployment after Experiment is finished.

For example we can use ResumeExperiment flag here: https://github.com/kubeflow/katib/blob/master/pkg/apis/controller/experiments/v1alpha3/experiment_types.go#L54.

1. ResumeExperiment: False if user wants to delete Suggestion after experiment is finished.
2. ResumeExperiment: True if user doesn't want to delete Suggestion after experiment is finished.
