NFS volumes created using podman volume create do not support specifying volume driver name

[toddhpoole]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description
After filing bug reports #4249, #4248, and #4247, and seeing all 3 resolved by the release of 1.6.2, we resumed trying to use podman volume create to create and mount NFS-backed volumes as originally announced in 1.6.1.

While re-creating an NFS-backed volume using 1.6.2, we're unable specify the volume driver name.

Documentation covering NFS volumes is non-existent, so we cannot tell if this is user error or broken code. As a part of resolving this issue, please consider adding NFS test cases to your build pipeline and expanding the Examples section of podman-volume-create.1.md with more examples, including NFS ones.

Steps to reproduce the issue:

1. Create a volume backed by an NFS filesystem while trying to specify the volume driver name (guessing at the NFS invocation here... again, there are no NFS examples in the documentation to reference).

[root@testhost ~]# podman volume create --driver=local --opt type=nfs --opt o=addr=192.168.2.126,rw --opt device=:/exports/test/ podman_vol_create_test2
Error: error running volume create option: not yet implemented

Describe the results you received:
podman volume create does not allow us to specify a volume driver name during volume creation.

Describe the results you expected:
podman volume create allows us to specify a volume driver name during volume creation.

I'm working on volume driver support separately; I'd expect it to be a Podman 1.7 feature. For now, I recommend omitting it if you're just specifying local; that will be used as the default.

Initial work here in #4548

@mheon This is still in progress correct?

[mheon]

On hold until I can get attach working and unblock Brent. Optimistically still hoping for this in 1.8 but realistically could slip to 1.9

[rhatdan]

Looks like we are waiting for 1.9?

[mheon]

Still on hold for Exec stuff. Honestly, on hold until Brent stops feeding me APIv2 work, heh

[rhatdan]

@mheon Reminder.

[mheon]

Need to talk with Brent about where this falls in the priorities stack, we still have significant work on Podmanv2

[rhatdan]

@mheon @baude Podman V2 is out, we have customers looking for docker volume support, I think it is time we start prioritizing this.

This is still ongoing as part of the volume work.
