* Move CPU count function to common, fix wrong CPU count in visited list

* Use CPU budget and CPU permits for optimizer tasks to limit utilization
* Respect configured thread limits, use new sane defaults in config
* Fix spelling issues
* Fix test compilation error
* Improve breaking if there is no CPU budget
* Block optimizations until CPU budget, fix potentially getting stuck
Our optimization worker now blocks until CPU budget is available to
perform the task.
Fix potential issue where optimization worker could get stuck. This
would happen if no optimization task is started because there's no
available CPU budget. This ensures the worker is woken up again to
retry.

* Remove numbers for automatic selection of indexing threads
* Inline max_workers variable
* Remove CPU budget from ShardTransferConsensus trait, it is in collection
* small allow(dead_code) => cfg(test)
* Remove now obsolete lazy_static
* Fix incorrect CPU calculation in CPU saturation test
* Make waiting for CPU budget async, don't block current thread
* Prevent deadlock on optimizer signal channel
Do not block the optimization worker task anymore to wait for CPU budget
to be available. That prevents our optimizer signal channel from being
drained, blocking incoming updates because the cannot send another
optimizer signal. Now, prevent blocking this task all together and
retrigger the optimizers separately when CPU budget is available again.
* Fix incorrect CPU calculation in optimization cancel test
* Rename CPU budget wait function to notify
* Detach API changes from CPU saturation internals
This allows us to merge into a patch version of Qdrant. We can
reintroduce the API changes in the upcoming minor release to make all of
it fully functional.

* Minor collection optimizer cleanup
* Make optimizers better aware of available vs soft deleted points
* Fix incorrect deleted state on proxy segment for double delete
* Rename upsert_vector to upsert_point, because we work with points
* Refactor point methods for more clear and consistent naming
* Replace internal_size in IdTracker with total_point_count
* Keep track of vector deletion count on storage creation
* Add sparse index optimizer, to optimize indexes with high deletion count
* Add minimum vector count threshold to sparse index optimizer
* Add sparse index optimizer test
* Use consistent naming, write vector in full everywhere
* Simplify vacuum optimizer a bit
* Merge sparse index optimizer into vacuum optimizer
* Improve update_from in segment builder by returning early
* More accurately count vectors in segment optimizer
* Remove random from vacuum optimizer tests to make them more reliable
* Don't expose the total points in segment info, use available points
* Process review feedback
* Compare available vectors against indexed ones in vacuum optimizer
This is much better than using the number of soft-deleted vectors when
the segment was created for calculations. Not to mention that value had
other problems as well.
* Remove create_deleted_vector_count field, update vacuum test parameters
* Potentially solve out of bound panic when building index
* Review fixes:
- Propagate deleted flags into payload hnsw building
- Use `total` number of points for building HNSW instead of number of
available points
- minor refactoring of `hnsw_config` copy -> clone
- Better detection of `indexed_points` in HNSW

* Exclude deleted vectors from HNSW graph building stage
* When estimating query cardinality, use available points as baseline
We should not use the total number of points in a segment, because a
portion of it may be soft deleted. Instead, we use the available
(non-deleted) points as baseline.
* Add plain search check to unfiltered HNSW search due to deleted points
* Cardinality sampling on available points, ignore deleted named vectors
* Estimate available vectors in query planner, now consider deleted points
In the query planner, we want to know the number of available points as
accurately as possible. This isn't possible because we only know the
number of deletions and vectors can be deleted in two places: as point
or as vector. These deletions may overlap. This now estimates the number
of deleted vectors based on the segment state. It assumes that point and
vector deletions have an overlap of 20%. This is an arbitrary
percentage, but reflects an almost-worst scenario.
This improves because the number of deleted points wasn't considered at
all before.
* Remove unused function from trait
* Fix bench compilation error
* Fix typo in docs
* Base whether to do plain search in HNSW upon full scan threshold
* Remove index threshold from HNSW config, only use full scan threshold
* Simplify timer aggregator assignment in HNSW search
* Remove vector storage type from cardinality function parameters
* Propagate point deletes to all its vectors
* Check for deleted vectors first, this makes early return possible
Since point deletes are now propagated to vectors, deleted points are
included in vector deletions. Because of that we can check if the vector
is deleted first so we can return early and skip the point deletion
check.
For integrity we also check if the point is deleted, if the vector was
not. That is because it may happen that point deletions are not properly
propagated to vectors.
* Don't use arbitrary vector count estimation, use vector count directly
Before we had to estimate the number of vectors (for a named vector)
because vectors could be deleted as point or vector. Point deletes are
now propagated to vector deletes, that means we can simply use the
deleted vector count which is now much more accurate.
* When sampling IDs, check deleted vecs before deleted points
* On segment consistency check, delete vectors for deleted points
* Fix vector delete state not being kept when updating storage from other
* Fix segment builder skipping deleted vectors breaking offsets
