PowerShell + .psd1 files - decouple environment configuration data from code

What is environment configuration data? Well, you might have heard the term 'configuration data' in usage with PowerShell DSC. The case for using configuration data is wherein all the input arguments are abstracted from the code being written so that this configuration data can be generated on the fly and passed to the underlying scripts or framework like DSC. For some of our solutions being deployed at the customer site, we require a lot of input parameters e.g. different network subnets for management and storage networks, AD/DNS information etc. Adding all these parameters to our input argument collector script was an error prone and tedious task since there were far too many input arguments. So instead of having a file to specify all input arguments was the preferred method. This also helped us while troubleshooting the deployments since a local copy of the input arguments always persisted.
