creating a volume of nfs type

Hi,

I am trying to mount a nfs share to a container using nerdctl. I am able to do that within a container using mount command, but creating a volume of type nfs seems not yet supported with nerdctl.

I am able to create nfs type volume using docker with below command:
```docker volume create --driver local --opt type=nfs --opt o=addr=,ro --opt device=: foo```

In nerdctl docs, it says --driver and --opt are not supported yet

```Unimplemented docker volume create flags: --driver, --opt```

If someone can share if there is another way to achieve this, or any information when this options would be supported will be really helpful.

Thanks!

Start with the nerdctl volume-create documentation and the documented unsupported --driver and --opt flags, then compare them with the provided Docker volume create command. Done means nerdctl can create and use an NFS volume with the requested driver, options, and device settings, with the documentation updated accordingly.
