Simply interface delete operation

Currently, we are using all the config data and using the merge operation, we are trying to make the interface outOfService before deleting the interface.

However, this is causing issue on the lab equipment because sometimes the config data passed before the delete operation gets rejected and the subsequent delete operation fails.

In order to avoid such stale interfaces, it be better to pass the just the following data to the interface:

1. Name of the interface
2. Type
3. Administrative state, set to OOS

This change is applicable to 1.2.1, 2.2.1 and 7.1 device models
