This change adds CDI device IDs to the ContainerAllocateResponse in the
device plugin API. This allows a device plugin to specify CDI devices
by their unique fully-qualified CDI device names using the related field
in the CRI specification.

This chagne introduces a helper to construct ContainerAllocateResponse instances.
Test cases are updated to use a new constructor accepting functional options
allowing the response contents to be set based on the test requirements.
This can then be extended to also test additional fields in the device plugin API
such as annotations which are not currently covered or new fields.

The GetAllocatableDevices, needed to support the podresources
API, doesn't take into account the device health when computing
its output.
In this PR we address this gap and add unit tests along the way
to prevent regressions. This gives us a good initial coverage,
E2E tests to cover this case are much harder to write, because
we would need to inject faults to trigger the unhealthy status.
We will evaluate if adding these tests into later PRs.

We want to make the return type of the GetDevices() method of the
podresources DevicesProvider interface consistent with
the newly added GetAllocatableDevices type.
This makes the code easier to read and reduces the coupling between
the podresourcesapi server and the devicemanager code.
No intended changes in behaviour, but the different return types
now requires some data massaging. Tests are updated accordingly.

It covers deviceplugin & cpumanager.
It has drawback, since cpuset and all other structs including cadvisor's keep
cpu as int, but for protobuf based interface is better to have fixed
int.
This patch also introduces additional interface CPUsProvider, while
DeviceProvider might have been extended too.
Checkpoint not covered by unit test.
