issue #1501: allow Closeable, top-level apis to be used as opposed to RestContext
issue #1501: add Closeable annotation to all top-level apis
added temporary workaround for AutoCloseable which will be deleted in jclouds 1.7
Adding listNodesByIds across the board.

Adding to both ListNodesStrategy and ComputeServiceAdapter. When
possible, does a query explicitly for the specified IDs. When not,
falls back on either listDetailsOnNodesMatching (for ListNodesStrategy
implementations and in BaseComputeService) or filters listNodes output
itself (in ComputeServiceAdapter).
