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.

Go will not allocate when reading from a map with a key cast from []byte to string.
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

This helps reduce confusion when UI-related targets fail without
directly indicating a version mismatch.
Automatically runs during UI builds and tests. The check is only
indicative.
The "go" binary can hard stop and print relevant messages on its
own for mismatches, thus not covered here.

Currently it allocates at least once on every recursion, and since
`append` gives no extra space for 1 or 2 elements, will allocate
several times for even modestly complex expressions.
Instead, allocate space for 4 elements to begin, and defer adding
another until we need it.
Add a note that `path` may get overwritten; this was true previously.
