Adds a new field to the `Request` type which specifies a timeout (in nanoseconds) for the request. This is propagated on method dispatch as a context timeout. There was some discussion here on supporting a broader "metadata" field (similar to grpc) that can be used for other things, but we ended up with a dedicated field because it is lighter weight and expect it to be used pretty heavily as is.... metadata may be added in the future, but is not necessary for timeouts. Also discussed using a deadline vs a timeout in the request and decided to go with a timeout in order to deal with potential clock skew between the client and server. This also has the side-effect of eliminating the protocol/wire overhead from the request timeout. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
