This patch makes the CRI `v1` API the new project-wide default version.
To allow backwards compatibility, a fallback to `v1alpha2` has been added
as well. This fallback can either used by automatically determined by
the kubelet.

- provide tests for static policy allocation, when init containers
requested memory bigger than the memory requested by app containers
- provide tests for static policy allocation, when init containers
requested memory smaller than the memory requested by app containers
- provide tests to verify that init containers removed from the state
file once the app container started

Remove init containers from the state file once the app container started,
it will release the memory allocated for the init container and can intense
the density of containers on the NUMA node in cases when the memory allocated
for init containers is bigger than the memory allocated for app containers.

node allocatable resources will be implemented under the memory manager.
