Grow the root disk

[alexis-eurecat]

I am using 0.13.0 version of vagrant-openstack-provider plugin, and Vagrant 2.2.9

I would like to increase the default size of the disk in the instance created by Vagrant. I tried with vagrant-disksize plugin and is just ignoring this parameter (as expected, because it is supposed to work only with VirtualBox).

I also tried with the experimental disk usage feature from Vagrant, with the same result.

I have been working with ESXi and it can be done via ESXi vagrant plugin, typing something like:

machine.vm.provider :vmware_esxi do |esxi|
  esxi.guest_boot_disk_size  = storage
end

Is there a way to do the same with Openstack provider?

Edit: I am not able to see the default created volumes, so I cannot stop VMs, detach, grow and reattach.
