ability to set environment variables.

[ramonskie]

we want to use a script.
where we need to access references of resources that are created by the arm template.

for example:
loadbalancer ip "[reference('pcf-lb-ip').ipAddress]",
dns name "[reference('dns-hostname').dnsSettings.fqdn]",

ideally this would be nice if they would be provided by the environment variables.
or even in settings file.
