      Fixes an issue where the containerd CNI config would be reloaded unnecessarily, potentially resulting in container restarts and brief network outages. This was caused by WICD not correctly accounting for carriage returns when identifying if the CNI config had been modified or not. This has been taken into account, and WICD will now only alter the CNI configuration when a change needs to be reverted.

      Steps to Reproduce:

      1. Bring up a Windows node
