[BUG][Azure connector] Sometime, the deployment of proxies failed

[jmaitrehenry]

Current Behavior

When Scrapoxy create many proxy in the same time, we have an error in the log:

[Nest] 1  - 06/21/2024, 12:49:54 PM   ERROR [RefreshConnectorsService] Error: Nic(s) in request is reserved for another Virtual Machine for 180 seconds. Please provide another nic(s) or retry after 180 seconds. Reserved VM: /subscriptions/xxx/resourceGroups/xxxx/providers/Microsoft.Compute/virtualMachines/spxw1-dolphin527328155-vm

It's a transient error and when scrapoxy create a new deployment, it works.

Expected Behavior

Scrapoxy create the proxy in the first try and without errors.

Steps to Reproduce

1. Create more than one proxy
2. Hope to have the error

@fabienvauchelles you can assign the issue to my and add a low priority flag as it's not really a problem, it just add some delay to the proxy creation.
