Describe the bug
When provisioning a Windows cluster using the vSphere node driver, Rancher will improperly generate the rancher-wins install file if multiple agent environment variables are provided. All environment variables will be rendered onto a single line, resulting in invalid powershell syntax. This does not reproduce for custom clusters.

To Reproduce
Provision a vSphere cluster with a windows node while specifying multiple agent environment variables

Result
The rancher-wins install script has multiple environment variables set on a single line, and the node will not come up

Expected Result
Only one variable is added on each line, and the node connects to the cluster

Screenshots

Additional context
As a workaround, you can manually adjust the install.ps1 file to ensure each environment variable is on a single line, then run the script

This is due to a missing newline when generating the install file, here
