Hyper-V: support for VM diagnostics

Registered by Alin Balutoiu

Currently, VM diagnostics is supported by KVM, VMWare and Xen. At the moment,
there is no support for VM diagnostics in the Hyper-V driver.

This blueprint proposes adding VM diagnostics support for the Hyper-V driver.

Whiteboard

As discussed in IRC today, the existing diagnostics REST API in v2.1 uses the old non-standard get_diagnostics compute API method, which is each virt driver providing a random dict of values. Before we add support for hyper-v, we need a microversion in the diagnostics REST API to use the newer standardized (for what was at the time v3) get_instance_diagnostics compute API method. That uses a mostly standard object for diagnostics that the virt drivers share, and then they have some extra room for custom values. But that's what hyper-v should start out using, which means this is dependent on a blueprint to add that microversion to use the newer code. -- mriedem 20160510
