* Limit the number of samples remote read can return.
- Return 413 entity too large.
- Limit can be set be a flag. Allow 0 to mean no limit.
- Include limit in error message.
- Set default limit to 50M (* 16 bytes = 800MB).

Looking at https://tech.townsourced.com/post/embedding-static-files-in-go/ (which was mentioned in the issue), vfsgen has all the needed features.
In particular:
- Reproducible builds (no issue with timestamping).
- Well maintained and relatively popular.
- Integration with go generate.
- Self-contained (no external dependency).

It was added 5 years ago by Matt and I'm not sure anyone ever used
it after public release (since we have /debug/pprof/heap as well).
It also lacked error checking and allows people to write to disk over HTTP.

Displaying all the dropped targets in the service-discovery page hurts
the Prometheus server as well as the browser when thousands of dropped
targets exist. This change limits this number to 1,000 and display the
number of active/total targets per scrape configuration.
Add warning when more than 100 targets are dropped

Fix race by properly locking access to scrape pools. Use separate mutex for information needed by UI so that UI isn't blocked when targets are being updated.
* web: replace deprecated InstrumentHandler()
This change replaces the deprecated InstrumentHandler function by the
equivalent functions from the promhttp package.
The following metrics are removed:
* http_request_duration_microseconds (Summary).
* http_request_size_bytes (Summary).
* http_requests_total (Counter).
And the following metrics are added instead:
* prometheus_http_request_duration_seconds (Histogram).
* prometheus_http_response_size_bytes (Histogram).
* promhttp_metric_handler_requests_in_flight (Gauge).
* promhttp_metric_handler_requests_total (Counter).
* Update github.com/prometheus/common/route package
* web: refactor using the new prometheus/common/route package
This adds a parameter to the storage selection interface which allows
query engine(s) to pass information about the operations surrounding a
data selection.
This can for example be used by remote storage backends to infer the
correct downsampling aggregates that need to be provided.
net.Listener converts 0.0.0.0 to :: which fails for hosts where IPv6 is
disabled. This change uses the original listen address parameter instead
of grpcl.Addr().String().
