Support multiple licensing products

[ejnarvala]

Changes

This change enables supporting unity floating license servers with multiple products configured, more info here.

• adds an action parameter unityLicensingProductIds
• updates services-config.json.template to set toolset based on unityLicensingProductIds. If this value is set to an empty string, it will use the server's default configuration, the same behavior as if the parameter was not included at alll
