This change updates `DirSize` to ignore `os.ErrNotExist` errors,
since they are expected during normal WAL cleanup. All other errors
continue to propagate.

Previously, BenchmarkRangeQuery would run each case with three data sizes
(1, 10, 100) and three range lengths (1, 100, 1000) for nine variations.
With 36 cases, running with `-count=6` to get dependable results, would
take 40-50 minutes in total.
This PR removes the middle option in both dimensions, thus shrinking to
four variations and about 20 minutes to run everything.

This is intended to make `intersectPostings` easier to follow.
Instead of cryptic `arr` and `cur`, name the members `postings` and
`current`.
Instead of updating `cur` to intermediate values encountered during
operations, introduce a local variable `target` meaning the ref we might
expect to find next, and only update `current` when an intersection is
found.
Name the function which implements seeking `Seek` instead of `doNext`.

Lets take the given example:
P1: [2, 5, 9, 18, 21]
P2: [3, 7, 14, 19, 21]
P3: [1, 21]
Currently, we would only advance through P1 and P2 until discovering
an intersection and then checking P3. In essence, the traversal order
was: 2, 3, 5, 7, 9, 14, 18, 19, 21 (intersection found).
With the proposed change, P3 is also examined even if P1 and P2
haven't found an intersection yet. This adjustment allows for the
possibility of skipping some iterations.
Post-change, the traversal order becomes: 2, 3, 21 (3 iterations instead of 9).

This check ensures that local ScrapeConfigs that only specify Legacy validation do not inherit the default global AllowUTF8 escaping setting, which is an invalid combination of settings.

AWS SDK v1 is end of life soon, so migrate to the V2 SDK. The credential loading should work more consistently with other projects that use the SDK and load credentials from the appropriate locations including from environment variables. This affects the EC2 and Lightsail service discovery features.

Also remove some yoloString calls in package `textparse` - call a more suitable library function.

* test(chunkenc): appending histograms with empty buckets and gaps
Append such native histograms that have empty buckets and gaps
between the indexes of those buckets.
There is a special case for appending counter native histograms to a chunk in TSDB: if we append a histogram that is missing some buckets that are already in chunk, then usually that's a counter reset. However if the missing bucket is empty, meaning its value is 0, then we don't consider it missing.
For this case to trigger , we need to write empty buckets into the chunk. Normally native histograms are compacted when we emit them , so this is very rare and compact make sure that there are no multiple continuous empty buckets with gaps between them.
The code that I've added in #14513 did not take into account that you can bypass compact and write histograms with many empty buckets, with gaps between them. These are still valid, so the code has to account for them.
Main fix in the expandIntSpansAndBuckets and expandFloatSpansAndBuckets function. I've also refactored them for clarity. Consequently needed to fix insert and adjustForInserts to also allow gaps between inserts.
I've added some new test cases (data driven test would be nice here, too many cases). And removed the deprecated old function that didn't deal with empty buckets at all.

Although these suffixes always need to be removed before querying metadata for
metrics that follow the Prometheus naming best practices, there can also be
metrics that don't follow these naming practices and have these suffixes
without being part of either a histogram or a summary metric.

Currently, the promql functions take the interface slice []parser.Value as an argument,
which is being implemented by the conrete types Vector, Matrix etc. This PR replaces
the interface with the concrete types, resulting in improved performance.
The inspiration for this PR came from #16698 which does this for binops.
I extended the idea to all promql functions
