Nornir Transform Function
Nornir includes a function that allows for the transformation of inventory data, a feature integrated within the Nornir platform itself. The documentation for Nornir 3.0 is somewhat sparse regarding the usage of Transform functions, so I often refer to the more comprehensive 2.5 documentation. According to the Nornir documentation:
A transform function is a plugin that manipulates the inventory independently from the inventory plugin used. Useful to extend data using the environment, a secret store or similar.
