VTEP Loopback IP for spine switches should not be identical

[SomaliRaven]

Different VTEP Support for Spine Switches

Affects Studio CloudVision_Studios/AVD Campus Studios/avd-campus.yaml .

Current behavior

If spine switch is enabled to have an activated vtep the interface loopback1 gets created spine switches always take the same vtep address for all spine switches.

This behavior is due to line 1297.

Requested behavior

In case the spine switches need a vtep a different ip address should be used for each spine switch. I believe that just removing lines 1296 and 1297 from the file should just work.
