[mamu0]

Motivation and Context

In view of the migration of the APIM in italynorth, this PR was created which contains the creation of all the resources that will point to the new APIM, it will be applied before making the backup and restore on the new APIM in ITN, so as to generate all the necessary APIs and products.
Subsequently, all the commented code will be uncommented in a specific PR and the imports of all those resources will be made.
Once the migration is finished, the files and resources relating to the weu APIM v2 will be deleted.
