Update this cloudstack driver to work with Test Kitchen version 3.2.2

[nrocco]

Description

This PR updates the existing cloudstack driver to support Test Kitchen version 3.2.2.

It supports Shared Network only and is tested with Ubuntu 20.04, FreeBSD 12.2 and Windows 2019 cloudstack images.

Any feedback/suggestions welcome.

I am hoping that this is a first towards including cloudstack in the list of supported plugins here https://kitchen.ci/docs/drivers/

Sorry this sat so long.

#46 ported the driver to the modern driver and transport API, so I am closing this as superseded. Your PR got there first and got the important parts right. #46 uses the same shape you did: wait_until_ready on the transport connection, with the CloudStack password passed through state. Your testing against real Ubuntu, FreeBSD and Windows 2019 images was the only real hardware evidence I had for the WinRM path, so it was useful to have your diff to check against.

Things yours does that #46 does not, now tracked separately: #51 name lookup instead of UUIDs, #49 error wrapping, #50 idempotent create, #52 rootdisksize, #53 post install script.

If you still use this driver and want to pick any of them up, please do.
