Terraform: cloudstack_instance should not require name parameter

[larstobi]

From the Terraform docs we can read:

name - (Required) The name of the instance. Changing this forces a new resource to be created.

From the CloudStack docs we can read:

| Parameter Name | Description | Required |
| --- | --- | --- |
| name | host name for the virtual machine | false |

I expect to be able create an instance with terraform without supplying a name and get the generated unique instance name from CloudStack (i.e. VM-3de42035-6ab5-4c84-b422-26ea8e454353).

What happens when I omit the name parameter is I get an error from Terraform:

Errors:
  * cloudstack_instance.test: "name": required field is not set

Hi @larstobi! Thanks for reporting this. I've opened a pull request at #5587 which should resolve this, and have CC'd in the maintainer of the CloudStack provider for review.
