Object-server: add periodic greenthread yielding during file read.
Currently, when object-server serves GET request and DiskFile reader iterate over disk file chunks, there is no explicit eventlet sleep called. When network outpace the slow disk IO, it's possible one large and slow GET request could cause eventlet hub not to schedule any other green threads for a long period of time. To improve this, this patch add a configurable sleep parameter into DiskFile reader, which is 'cooperative_period' with a default value of 0 (disabled).
