For remote hypervisor, the configmap, secrets, downward-api or project-volumes are
copied from host to guest. This patch watches for changes to the host files
and copies the changes to the guest.
Note that configmap updates takes significantly longer than updates via downward-api.
This is similar across runc and Kata runtimes.

This PR is a continuing work for (kata-containers#3679).
This generalizes the previous VFIO device handling which only
focuses on PCI to include AP (IBM Z specific).

Initial VFIO-AP support (#578) was simple, but somewhat hacky; a
different code path would be chosen for performing the hotplug, and
agent-side device handling was bound to knowing the assigned queue
numbers (APQNs) through some other means; plus the code for awaiting
them was written for the Go agent and never released. This code also
artificially increased the hotplug timeout to wait for the (relatively
expensive, thus limited to 5 seconds at the quickest) AP rescan, which
is impractical for e.g. common k8s timeouts.
Since then, the general handling logic was improved (#1190), but it
assumed PCI in several places.
In the runtime, introduce and parse AP devices. Annotate them as such
when passing to the agent, and include information about the associated
APQNs.
The agent awaits the passed APQNs through uevents and triggers a
rescan directly.

Generalize VFIO devices to allow for adding AP in the next patch.
The logic for VFIOPciDeviceMediatedType() has been changed and IsAPVFIOMediatedDevice() has been removed.
The rationale for the revomal is:
- VFIODeviceMediatedType is divided into 2 subtypes for AP and PCI
- Logic of checking a subtype of mediated device is included in GetVFIODeviceType()
- VFIOPciDeviceMediatedType() can simply fulfill the device addition based
on a type categorized by GetVFIODeviceType()

e.g., split_vfio_option is PCI-specific and should instead be named
split_vfio_pci_option. This mutually affects the runtime, most notably
how the labels are named for the agent.
