Add SMB Shares to Docker

[Hutch79]

Is your feature request related to a problem? Please describe.

Currently, you can add SMB Shares to CasaOS. It's great to have this feature, but at the moment it is not possible (or maybe I'm just blind) to add an SMB share to a Docker container.

Describe the solution you'd like

To be able to add an SMB share to a Docker container like any other local folder.
