IndexShards normally sees the indexes as opaque, so there is no way to factrorize the coarse quantizer.
This diff introduces IndexIVFShards that handles IVF indexes with a common quantizer so that the quantization is computed only once.

Summary:
This diff fixes https://github.com/facebookresearch/faiss/issues/1412
There were various inconsistencies in how the shard and replica wrappers updated their internal state as the sub-indices were updated. This makes the two container classes work in the same way with similar synchronization functionality.
