Feature description

In notebooks / dashboard, I'd like to mount in as a volume a file from a configmap. This might be either via odh notebook controller or odh dashboard. If via Dashboard, the filenames from which configmaps to which volumeMount targetLocation would best be specified centrally in Dashboard Admin Section. A multidimensional array maybe.

Describe alternatives you've considered

Manually baking into container workbench docker image builds the files.
This means, though, having to create different container images for different files.
The solution to mount such files via configmap in the workbench namespace is more elegant.
