Initial release

This is the initial release of the gpuallocator package.

The gpuallocator package provides a generic abstraction for performing GPU allocations independent of the larger system the gpuallocator is integrated with.

The abstractions provided by this package are not meant to do actual "allocation" of GPUs to any specific entity, but rather run the algorithm responsible for deciding which GPUs should be chosen for allocation based on the set of GPUs available in the system and the number of GPUs being requested.

Different policies can be hooked in to run different allocation algorithms depending on the specific needs of the system.
