It got pretty ugly after the last commit. Refactor it so that we first
collect all the key ranges that need to be written out into a list of
tasks, then partition the tasks into image layers, and then write them
out. This will be much easier to parallelize, but that's not included
in this commit yet.
It runs the command successfully. Doesn't try to attach it to the
pageserver on it yet

## Problem
Metrics event idempotency keys differ across S3 and Vector. The events
should be identical.
Resolves#8605.
## Summary of changes
Pre-generate the idempotency keys and pass the same set into both
metrics sinks.

Implement the timeline specific `archival_config` endpoint also in the
storage controller.
It's mostly a copy-paste of the detach handler: the task is the same: do
the same operation on all shards.
Part of #8088.
## Problem
This is a followup to #8783
- The old blocking ensure_attached function had been retained to handle
the case where a shard had a None generation_pageserver, but this wasn't
really necessary.
- There was a subtle `.1` in the code where a struct would have been
clearer
Closes#8819
## Summary of changes
- Add ShardGenerationState to represent the results of peek_generation
- Instead of calling ensure_attached when a tenant has a non-attached
shard, check the shard's policy and return 409 if it isn't Attached,
else return 503 if the shard's policy is attached but it hasn't been
reconciled yet (i.e. has a None generation_pageserver)
The test is very rudimentary, it only checks that before and after
tenant deletion, we can run `scan_metadata` for the safekeeper node
kind. Also, we don't actually expect any uploaded data, for that we
don't have enough WAL (needs to create at least one S3-uploaded file,
the scrubber doesn't recognize partial files yet).
The `scan_metadata` scrubber subcommand is extended to support either
specifying a database connection string, which was previously the only
way, and required a database to be present, or specifying the timeline
information manually via json. This is ideal for testing scenarios
because in those, the number of timelines is usually limited,
but it is involved to spin up a database just to write the timeline
information.
The pull request https://github.com/neondatabase/neon/pull/8679
explicitly mentioned that it will evict layers earlier than before.
Given that the eviction metrics is solely based on eviction threshold
(which is 86400s now), we should consider the early eviction and do not
fire alert if it's a covered layer.
## Summary of changes
Record eviction timer only when the layer is visible + accessed.

## Summary of changes
- Setting default io_buffer_alignment to 512 bytes.
- Fix places that assumed `DEFAULT_IO_BUFFER_ALIGNMENT=0`
- Adapt unit tests to handle merge with `chunk size <= 4096`.
## Testing and Performance
We have done sufficient performance de-risking.
Enabling it by default completes our correctness de-risking before the
next release.

When implementing bottom-most gc-compaction, we analyzed the structure
of layer maps that the current compaction algorithm could produce, and
decided to only support structures without delta layer overlaps and LSN
intersections with the exception of single key layers.
## Summary of changes
This patch adds the layer map valid check in the storage scrubber.

## Problem
`promote-compatibility-data` job got broken and slightly outdated after
- https://github.com/neondatabase/neon/pull/8552 -- we don't upload
artifacts for ARM64
- https://github.com/neondatabase/neon/pull/8561 -- we don't prepare
`debug` artifacts in the release branch anymore
## Summary of changes
- Promote artifacts from release PRs to the latest version (but do it
from `release` branch)
- Upload artifacts for both X64 and ARM64
## Problem
Live migration retries when it fails to notify the compute of the new
location. It should sleep between attempts.
Closes: https://github.com/neondatabase/neon/issues/8820
## Summary of changes
- Do an `exponential_backoff` in the retry loop for compute
notifications
`safekeeper::random_test test_random_schedules` debug test takes over 2
minutes to run on our arm runners. Running it 6 times with pageserver
settings seems redundant.
In #8863 I replaced the threadpool with tokio tasks, but there was a
behaviour I missed regarding cancellation. Adding the JoinHandle wrapper
that triggers abort on drop should fix this.
Another change, any panics that occur in password hashing will be
propagated through the resume_unwind functionality.
Removes additional async_trait usages from safekeeper and neon_local.
Also removes now redundant dependencies of the `async_trait` crate.
