Implement the ability to evaluate runtime context of the Autoscaling Service module specifically allow the following:

* evaluate configurations on Autoscaling Service to read the rendered data at runtime as an example

<+configFile.getAsString("CONFIG_FILE_ID")>: Get config file contents as plain text.

<+configFile.getAsBase64("CONFIG_FILE_ID")>: Get config file contents with Base64-encoding
