- The `Allocate` method will try to allocate the memory according to the affinity hints
saved under the `TopologyManager` store. If the store does not have any hints for the memory
it will call `getDefaultHint` to get the default hint. If the affinity does not satisfy
the memory request, it will call `extendTopologyManagerHint` to extend the topology hint to
satisfy the memory request. Once it has the preferred hint, it will allocate the memory and
update the the memory manager state accordingly.
- The `RemoveContainer` will release the allocated memory and update the memory manager state accordingly.
- The `GetTopologyHints` method will try to re-generate topology hints when the container already presents
under the memory manager state. If it does not present it will call `calculateHints` to get topology hints.
The `calculateHints` uses an approach similar to the one used under the CPU manager:
1. If the container memory request can be satisfied by the single NUMA node, it will not allocate the memory from
more than one NUMA node and it will set only single NUMA hints as the preferred one.
It can affect the density, but it gives us guarantees regarding the NUMA alignment.
2. The NUMA node used in the multi NUMA assignment can not be used in the single NUMA assignment.
And the NUMA node used in the single NUMA assignment can not be used in the multi NUMA assignment.
3. Only hints with NUMA node that have enough memory will be returned.
