Install dependencies to register MAC address to ISP

Summary:
When the CARP device becomes active, the upstream router needs to be notified
of the address MAC of the device where to route traffic for the shared address.

For dedicated servers, the router is managed by our provider, not by us.
The first implementation is for hyper-001, hosted at OVH. An API is available
to update the MAC address.

We develop a Python script solution to trigger the API. Credentials are stored
in Vault.
