e7256e08d3 kubelet dra: add checkpointing mechanism in the DRA Manager
The checkpointing mechanism will repopulate DRA Manager in-memory cache on kubelet restart.
This will ensure that the information needed by the PodResources API is available across
a kubelet restart.

The ClaimInfoState struct represent the DRA Manager in-memory cache state in checkpoint.
It is embedd in the ClaimInfo which also include the annotation field. The separation between
the in-memory cache and the cache state in the checkpoint is so we won't be tied to the in-memory
cache struct which may change in the future. In the ClaimInfoState we save the minimal required fields
to restore the in-memory cache.

bc6c7fa912 logging: fix names of keys
The stricter checking with the upcoming logcheck v0.4.1 pointed out these names
which don't comply with our recommendations in
https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/migration-to-structured-logging.md#name-arguments.

ae0f38437c kubelet: add support for dynamic resource allocation
Dependencies need to be updated to use
github.com/container-orchestrated-devices/container-device-interface.

It's not decided yet whether we will implement Topology support
for DRA or not. Not having any toppology-related code
will help to avoid wrong impression that DRA is used as a hint
provider for the Topology Manager.
