Description

The azurecaf_name resource (Azurecaf provider) implements a set of methodologies in applying a consistent resource naming using the default Microsoft Cloud Adoption Framework for Azure recommendations.

The global settings which propagate names, tags etc from the launchpad to subsequent landingzones currently do not have an option to configure for suffixes. This PR attempts to provide the support for suffixes.
