Defines asynchronous librados operations that satisfy all of the "Requirements on asynchronous operations" imposed by the C++ Networking TS [1] in section 13.2.7. These operations are implemented in terms of boost::asio, but the interfaces themselves are free of boost types - this makes the transition to std::net trivial when it's available. These interfaces conform to the Extensible Asynchronous Model [2] that originated in boost::asio. This model allows the last 'handler' argument to either be a callback that gets the result, a coroutine yield_context that will suspend until completion, or a 'use_future' tag to request the result in a std::future (see the unit tests for examples of each). The 'Extensible' part also enables further integration with new frameworks. For now, only async_read(), async_write(), and the read/write variants of async_operate() are provided.
