Don't sort postings if we only have one block.
...
Sorting the heads postings can be quite slow.
We only need sorted series when merging with another
querier, so only sort then.
This will make big queries that only touch the head faster,
though queries that touch both the head and a block will still
be the same speed. This probably won't help much with graphing
unless the range is under an hour, however it should make most
recording rules faster.
Add gaurantee that remote read streaming produces sorted series.
PromQL benchmarks for histograms show only 2-3% improvement, but
they're only over 1k series.

Deprecate DeduplicateSeriesSet() in favor of NewMergeSeriesSet().
...
Federation makes use of dedupedSeriesSet to merge SeriesSets for every
query into one output stream. If many match[] arguments are provided,
many dedupedSeriesSet objects will get chained. This has the downside of
causing a potential O(n*k) running time, where n is the number of series
and k the number of match[] arguments.
In the mean time, the storage package provides a mergeSeriesSet that
accomplishes the same with an O(n*log(k)) running time by making use of
a binary heap. Let's just get rid of dedupedSeriesSet and change all
existing callers to use mergeSeriesSet.

Remote storage reads based on oldest timestamp in primary storage ( #3129 )
...
Currently all read queries are simply pushed to remote read clients.
This is fine, except for remote storage for wich it unefficient and
make query slower even if remote read is unnecessary.
So we need instead to compare the oldest timestamp in primary/local
storage with the query range lower boundary. If the oldest timestamp
is older than the mint parameter, then there is no need for remote read.
This is an optionnal behavior per remote read client.
