Julius Volz 099df0c5f0 Migrate "golang.org/x/net/context" -> "context" (#3333) 
In some places, where ctxhttp or gRPC are concerned, we still need to use the
old contexts.

Fabian Reinartz 437f51a85f Fix cache maintenance on changing metric representations 
We were not properly maintaining the scrape cache when the same metric
was exposed with a different string representation.
This overall reduces the scraping cache's complexity, which fixes the
issue and saves about 10% of memory in a scraping-only Prometheus
instance.

Fabian Reinartz 5bed8af4cb retrieval: pool scrape buffers 
This adds a bucketed buffer pool to the scrapers so we don't have to
allocate a new buffer on each scrape or hold it fixed to the scrape
loop.

The latter can consume significant amounts of unused memory, e.g. 4GB
when scraping 2MB /metrics from 2000 targets.

Fabian Reinartz 9ea748e745 Don't reallocate label set if still known 
If the storage deprecates a ref, we have to re-insert with the full
label set. Typically that doesn't correlate with a new series being
created.
We can still use the allocated label set from before.
