test: api/cloudInit tests will fail

[NemoDacremont]

What happens

When running api/cloudInit tests on a fresh proxmox (v8.4.14) install, the tests will fail, the logs are following :

--- FAIL: Test_Cloud_Init_VM (0.12s)
    cloudinit_test.go:23:
                Error Trace:    /home/ndacremont/Documents/explore/proxmox-api-go/test/api/CloudInit/cloudinit_test.go:23
                Error:          Received unexpected error:
                                error creating network: 400 Parameter verification failed.
                                                 api response: {"errors":{"iface":"interface already exists"},"message":"Parameter verification failed.\n","data":null}
                                                 params: {"autostart":true,"iface":"vmbr0","node":"pve","type":"bridge"}
                Test:           Test_Cloud_Init_VM
FAIL
FAIL    github.com/Telmate/proxmox-api-go/test/api/CloudInit    0.121s

Expected

The test shouldn't fail because the interface already exists

I might try to fix it sooner or later
