Metric for chunks stored should take acount of de-duplication

[bboreham]

Currently cortex_ingester_chunks_stored_total reports all chunks that were sent to the store; below that level the store may avoid the write and return success, but this isn't visible.

Similarly cortex_ingester_chunk_stored_bytes_total

(Note these metrics were renamed in April 2020)

(Note that even when the Cortex code doesn't detect duplication the underlying store may do so; there isn't much we can do about that in real-time)

chunk_store_stored_chunks_total and cortex_chunk_store_stored_chunk_bytes_total now report per user metric. And this is after deduping :)

See: #2463

I see nothing in the description or CHANGELOG for #2463 about deduping.

I added this in #2579 (per @gouthamve's request).
