OBM driver for Intel AMT

[henn]

We may want to support Intel AMT as an OBM driver at some point in order to support desktop/laptop systems in HIL. Our use case would be supporting the dev laptops we use in Secure Cloud.

Due to security issues, admins would likely only want to expose AMT in relatively trusted environments. My understanding is that AMT usually shares the NIC with the OS via a bridge, preventing us from sticking the AMT interfaces on a separate network without user-access like we recommend for IPMI.
