Swati Sehgal 937d330393 node: topologymgr: Remove ResourceAllocator as TM is always enabled 
With Topology Manager enabled by default, we no longer need
`resourceAllocator` as Topology Manager serves as the main
PodAdmitHandler completely responsible for admission check
based on hints received from the hintProviders and the
subsequent allocation of the corresponding resources to a
pod as can be seen here:
https://github.com/kubernetes/kubernetes/blob/v1.26.0/pkg/kubelet/cm/topologymanager/scope.go#L150

With regard to DRA, the passing of `cm.draManager` into
resourceAllocator seems redundant as no admission checks
(and allocation of resources handled by DRA) is taking place
in `Admit` method of resourceAllocator. DRA has a completely
different model to the rest of the resource managers where
pod is only scheduled on a node once resources are reserved
for it. Because of this, admission checks or waiting for
resources to be provisioned after the pod has been scheduled
on the node is not required.

Before making the above change, it was verified that DRA Manager
is instantiated in `NewContainerManager`:
https://github.com/kubernetes/kubernetes/blob/v1.26.0/pkg/kubelet/cm/container_manager_linux.go#L318
