Eric Ernst 20419feaac cri, sandbox: pass sandbox resource details if available, applicable ...

CRI API has been updated to include a an optional `resources` field in the
LinuxPodSandboxConfig field, as part of the RunPodSandbox request.

Having sandbox level resource details at sandbox creation time will have
large benefits for sandboxed runtimes. In the case of Kata Containers,
for example, this'll allow for better support of SW/HW architectures
which don't allow for CPU/memory hotplug, and it'll allow for better
queue sizing for virtio devices associated with the sandbox (in the VM
case).

If this sandbox resource information is provided as part of the run
sandbox request, let's introduce a pattern where we will update the
pause container's runtiem spec to include this information in the
annotations field.
