Central Net Key storage cache for multiple Nodes

The strategy for Bluetooth Mesh is to allow each application that want to use mesh services to operate as an independant Node on one or more Mesh networks.

To enable this, at the lowest network layer, we are creating a cache of Network Keys and associated credentials (NIDs, Privacy Keys, Encryption Keys, etc). This will allow Network decryption to be done once per incoming packets, without requiring each "Node" on the local device to handle them redundantly.
