[Request]: Storage - Allow mounting named volumes read-only to multiple containers

### Feature or enhancement request details

Add support for mounting a single named volume in read-only mode across multiple containers simultaneously. This would allow safe sharing of common datasets, ML models, or configuration files without duplication, ensuring consistency and reducing disk usage.

Example usage:
```
container run -v mydata:/data:ro container1
container run -v mydata:/data:ro container2
```

Things to consider:
* Allow multiple concurrent read-only mounts of the same named volume.
* Maintain exclusive access rules for read-write mounts to prevent conflicts.
* Ensure volume lifecycle and reference counting are updated to handle shared mounts.
