Jing Xu 8f98230f20 Map a resource to multiple signals in eviction manager 
It is possible to have multiple signals that point to the same type of
resource, e.g., both SignalNodeFsAvailable and
SignalAllocatableNodeFsAvailable refer to the same resource NodeFs.
Change the map from map[v1.ResourceName]evictionapi.Signal to
map[v1.ResourceName][]evictionapi.Signal

Jing Xu bb1920edcc Fix issues for local storage allocatable feature 
This PR fixes the following issues:
1. Use ResourceStorageScratch instead of ResourceStorage API to represent
local storage capacity
2. In eviction manager, use container manager instead of node provider
(kubelet) to retrieve the node capacity and reserved resources. Node
provider (kubelet) has a feature gate so that storagescratch information
may not be exposed if feature gate is not set. On the other hand,
container manager has all the capacity and allocatable resource
information.
