Because overlay is a builtin driver and global allocation of overlay
resources is probably going to happen in a different node (a single
node) and the actual plumbing of the network is probably going to happen
in all nodes, it makes sense to split the functionality of allocation
into two different packages. The central component(this package) only
implements the NetworkAllocate/Free apis while the distributed
component(the existing overlay driver) implements the rest of the driver
api. This way we can reduce the memory footprint overall.

Added NetworkAllocate and NetworkFree apis to the list of
driver apis. The intention of the api is to provide a
centralized way of allocating and freeing network resources
for a network which is cross-host.
