- 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).

When prom2 came out the storage querier interface consolidated to a
single Select() method. While doing this it makes it impossible as the
implementer of the querier to know if you are being called for metadata
or actual data. The workaround has been to check if the SelectParams are
nil, which the federation call is always nil. This has 2 negative
consequences (1) remote implementations interpret this as a metadata
call, which makes the federation endpoint return nothing. (2) this means
that the storage implementations don't get the same information passed
down to them as far as SelectParams goes.
This diff simply adds SelectParams to the Select() call in the
federation handler

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).

* Add Start/End to SelectParams
* Make remote read use the new selectParams for start/end
This commit will continue sending the start/end time of the remote read
query as the overarching promql time and the specific range of data that
the query is intersted in receiving a response to is now part of the
ReadHints (upstream discussion in #4226).
* Remove unused vendored code
The genproto.sh script was updated, but the code wasn't regenerated.
This simply removes the vendored deps that are no longer part of the
codegen output.

Displaying all the dropped targets in the service-discovery page hurts
the Prometheus server as well as the browser when thousands of 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.
