We know the max size of our map so we can create it with that information and avoid extra allocations

This commit introduces a new metric to count the number of failed
requests to Linode's API when using Linode SD. Resolves#10672, inspired
by #10476.
_Note_: this doens't count failures when polling the `/account/events`
endpoint, as a `401` there is how we determine if the supplied token has
the needed API scopes to do event polling vs full refreshes each
interval.

On macOS, the TestTombstoneCleanRetentionLimitsRace performs very
poorly. It takes more than a second to write out one block, and as it
writes 400 of them, we run into the 10-minute test timeout frequently.
While this doesn't fix the actual performance issue, breaking each
iteration into a subtest makes the test pass reliably (because each
iteration comfortably finishes in under a minute).

Relax indentation to allow non-indented sequences. This helps with

"Labels is a sorted set of labels. Order has to be guaranteed upon
instantiation." says the comment, so fix all the tests that break this
rule.
For `BenchmarkLabelValuesWithMatchers()` and
`BenchmarkHeadLabelValuesWithMatchers()` the amount of work done changes
significantly if you put the labels in order, because all series refs
get neatly partitioned by the `tens` label, so I renamed the labels
to maintain the previous behaviour.

* Send target and metadata cache in context (again)
The previous attempt was rolled back in #10590 due to memory issues.
`sl.parentCtx` and `sl.ctx` both had a copy of the cache and target info
in the previous attempt and it was hard to pin-point where the context
was being retained causing the memory increase.
I've experimented a bunch in #10627 to figure out that this approach doesn't
cause memory increase. Beyond that, just using this info in _any_ other context
is causing a memory increase.
The change fixed a bunch of long-standing in the OTel Collector that the
community was waiting on and release is blocked on a few downstream distrubutions
of OTel Collector waiting on a fix. I propose to merge this change in while
I investigate what is happening.

If FlushAndShutdown is called with a full batchQueue, and then Batch is
called rather than the normal path of reading from a queue a deadlock
might be encountered. Rather than having FlushAndShutdown having
blocking code while holding a lock retry sending the batch every second.

* Add a test with variable samples rate append
This test overflows the chunk created in memseries, and the total amount
of samples in the (only) mmapped chunk is 29, instead of the 65565
appended ones.

* Cut new chunk when rate prediction was wrong
When appending samples at a slow rate, and then appending at a higher
rate, the prediction we made to cut a new chunk is no longer valid.
Sometimes this can even cause an overflow in the chunk, if more samples
than uint16 can hold are appended.
