Create stale markers when a target is stopped.
...
When a target is no longer returned from SD stop()
is called. However it may be recreated before the
next scrape interval happens. So we wait to set stalemarkers
until the scrape of the new target would have happened
and been ingested, which is 2 scrape intervals.
If we're shutting down the context will be cancelled,
so return immediately rather than holding things up for potentially
minutes waiting to safely set stalemarkers no newer than now.
If the server starts immediately back up again all is well.
If not, we're missing some stale markers.

Don't fail scrape if one sample violates ordering.
...
In Prometheus 1.x one sample that is out of order
or that has a duplicate timestamp is discarded, and
the rest of the scrape ingestion continues on.
This will now also be true for 2.0.

Add stale markers on parse error.
...
If we fail to parse the result of a scrape,
we should treat that as a failed scrape and
add stale markers.

Treat a failed scrape as an empty scrape for staleness.
...
If a target has died but is still in SD, we want the previously
scraped values to go stale. This would also apply to brief blips.

retrieval: cache series references, use pkg/textparse
...
With this change the scraping caches series references and only
allocates label sets if it has to retrieve a new reference.
pkg/textparse is used to do the conditional parsing and reduce
allocations from 900B/sample to 0 in the general case.

Add sample_limit to scrape config.
...
This imposes a hard limit on the number of samples ingested from the
target. This is counted after metric relabelling, to allow dropping of
problemtic metrics.
This is intended as a very blunt tool to prevent overload due to
misbehaving targets that suddenly jump in sample count (e.g. adding
a label containing email addresses).
Add metric to track how often this happens.
