Also change the SD page setting for this to be in localStorage, as on the
other pages.

* Fix storage/remote.pool interned refs count and flaky test
I saw TestIntern_MultiRef_Concurrent failing on a different PR saying 'expected refs to be 1 but it was 2'.
I took a look, and it definitely can be racy, especially with a time.Sleep() of just 1ms.
I'm fixing that by explicitly waiting until it has been released, and by repeating that 1000 times, otherwise it's just a recipe for a future flaky test.
OTOH, I also took a look at the implementation and saw that we were not holding the RLock() when increasing the references count, so when releasing there was a race condition for the cleanup, I fixed that by holding RLock() while increasing the references count.

This test consistently fails missing ~10 series.
If it doesn't fail on your machine, just increase totalSeries, that's
how race conditions work.

The new metric_name_escaping_scheme config option works in parallel with metric_name_validation_scheme and controls which escaping scheme is requested when scraping. When not specified, the scheme will request underscores if the validation scheme is set to legacy, and will request allow-utf-8 when the validation scheme is set to utf8. This setting allows users to allow utf8 names if they like, but explicitly request an escaping scheme rather than UTF-8.

The `:=` causes new variables to be created, which means the outer
slice stays at nil, and new memory is allocated every time round the
loop.

No need to validate, track, add sample, add exemplar if series isn't
going to be ingested. Basically this is the same as if this series was
dropped by relabelling.

[BUILD] Remove Go toolchain line
It doesn't reflect the version we use for CI builds, which is controlled by .promu.yml.
As such, I cannot see any justification to keep this line: it isn't necessary and it could confuse people.

* ruler notifier: make batch size configurable
In Mimir we experimented with setting a higher value for the batch size.
A 4x increase in batch size decreased the time to process a single notification by about 2x.
This reduces the processing time of the notifications queue and increases the throughput of the queue.

This is just IMO, but getting my inbox flooded every month with hundreds of
dependabot PRs is annoying, even if I don't end up handling most of them myself
(thanks to others who do!). And then philosophically, I don't know if this is
even the right approach. I don't think that whoever merges these PRs actually
has the capacity or the knowledge to check that everything is still working as
expected. Often subtle things can break after package updates, like a class
name from an npm package not fitting to a style definition in our code anymore
(as happened once with e.g. codemirror in the past, and nobody noticed when
merging, and that bug is still present in Thanos' port of our UI). And you
can't look in detail at the UI for every little PR that dependabot sends.
Node module dependencies are inherently very noisy because there are so many of
them, but I think a better approach would be to update them maybe once or twice
a year (or whenever really needed), with all deps updated together, at a time
when a maintainer has the time to really look at things carefully, and then do
a comprehensive manual check of the UI to see that everything is still behaving
as before.
