create_params_lxc: storage parameter doesn't support size

[ThomasLamprecht]

The storage parameter is for the storage only, nothing more.
Use the rootfs parameter to correctly sent the the disk size
and the storage to the PVE API2.

This patch helped me a lot, while trying to use test-kitchen + kitchen-vagrant + vagrant-proxmox. It would be nice to see this patch applied shortly.

I've also discovered that the storage parameter is not the right thing to use for this, that rootfs is the correct argument. This needs to be updated to work with recent versions of Proxmox for LXC containers.

@tadman try my fork please https://github.com/lehn-etracker/vagrant-proxmox we use it only with LXC and Proxmox 4.4

[ThomasLamprecht]

@tadman yes, my pull request would exactly do that, sadly @telcat seems to be inactive or have no interest in maintaining this anymore.
@lehn-etracker fork should give you what you want :)

If the Telcat version is defunct then this is a candidate for replacement. This is the version referenced in the Vagrant documentation, so if the @lehn-etracker version is more up to date it'd be nice if that one was also published as a gem and linked accordingly if the license allows for such things, which it should since this is under the MIT license.

I wasn't able to get things working with this version yet, I ran into other issues, but I'll keep trying to get it working.
