gnmi set request failed: rpc error: code = InvalidArgument desc = VNI is already used in VRF

[pau-hedgehog]

Probably linked to:

• Dynamic loopback allocation can still cause issues on reuse #377
• Seems like L3 config exist error is caused by moving Loopback workaround between VRFs #628

When running multiple times:

./hhfab-hhnet vlab vpcs -f

I get:

13:52:57 INF Switches status ready="[leaf-02 leaf-03 leaf-04 leaf-05 spine-01 spine-02]" notReady=[leaf-01]
