### Describe Your Changes
fsync() ensures that the data is written to disk. In production this is
needed for data durability. However, during the development, when the
unit tests are run, this level of durability is not needed. Therefore
fsync() can be disabled which will makes test runs two times faster.
The disabling is done by setting the `DISABLE_FSYNC_FOR_TESTING`
environment variable. The valid values for this variable are the same as
the values of the arg of `go doc strconv.ParseBool`:
```
1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False.
```
Any other value means `false`.
The variable is set for all test build targets. Compare running times:
Build Target | DISABLE_FSYNC_FOR_TESTING=0 | DISABLE_FSYNC_FOR_TESTING=1
----------------- | ------------------------------------------------ |
-------------------------------------------------
make test | 1m5s | 0m22s
make test-race | 3m1s | 1m42s
make test-pure | 1m7s | 0m20s
make test-full | 1m21s | 0m32s
make test-full-386 | 1m42s | 0m36s
When running tests for a given package, fsync can be disabled as
follows:
```shell
DISABLE_FSYNC_FOR_TESTING=1 go test ./lib/storage
```
Disabling fsync() is intended for testing purposes only and the name of
the variables reflects that.
What could also have been done but haven't:
- lib/filestream/filestream.go: `Writer.MustFlush()` also uses f.Sync()
but nothing has been done to it, because the Writer.MustFlush() is not
used anywhere in the VM codebase. A side question: what is the general
policy for the unused code?
- lib/filestream/filestream.go: Writer.Write() calls `adviceDontNeed()`
which calls unix.Fdatasync(). Disabling it could potentially improve
running time, but running tests with this code disabled has shown
otherwise.

### Describe Your Changes
Forcefully set permissions for release binaries to 1000:1000. This helps
to avoid issues such as
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6788 on
systems with limitations around UID:GID configuration.
"1000" UID and GID is widely used by linux distributions for the first
user in the system.

### Describe Your Changes
Implement spellcheck command:
- add cspell configuration files
- dockerize spellchecking process
- add Makefile targets
This PR adds a standalone `make spellcheck` target to check `docs/*.md` files for spelling
errors. The target process is dockerized to be run in a separate npm environment.
Some `docs/` typo fixes also included.

(cherry picked from commit 1c155a0cd1)
The `make clean-checkers` command may be useful when the locally installed checker apps are too old,
so they must be updated to the newly requested versions by `make check-all`. In this case the fix is to run
make clean-checkers check-all
This reverts commit 92b22581e6.
Reason for revert: too complex and slow approach for spellchecking task.
This approach may significantly slow down development pace. It also may take non-trivial
amounts of additional time and resources at CI/CD because of all this npm shit at cspell directory.
Note to @arkid15r : the idea with the ability to run spellchecker on all the VictoriaMetrics
codebase is great. But this shouldn't be mandatory pre-commit check. It is enough to have
a Makefile rule like `make spellcheck`, which could be run manually whenever spellcheck is needed
(e.g. once per month or once per quarter).
This reverts commit 20b18e9feb.
Reason for revert: running goimports on `make check-all` introduces the following issues:
- It runs only on modified files, which weren't commited yet into git repository.
This means the formatting for the remaining files becomes different comparing to the formatting
for the changed files. This also means that the goimports has no any effect
at github actions and when the changed code is already commited to git repository.
- `gomiports` performs formatting in the same way as gofmt, so `make fmt` becomes unnecessary.
But when `gofmt` is substituted with `goimports`, then it performs unnecessary formatting for *.qtpl.go files.
It is possible to make a hack, which will prepare a list of all the *.go files at lib/ and app/
without the *.qtpl.go files, and then feed this list to `goimports`, but this looks too fragile
for the task of just fixing the ordering of Go imports.
So it is better to leave source code formatting as is with `gofmt`, while manually fixing improper ordering
of Go import from time to time in dedicated commits until better solution arises.
* make: add goimports task
Adds task to fix imports formatting implace.
Formats imports into:
- native library
- external libraries
- local packages based on github.com/VictoriaMetrics/VictoriaMetrics prefix

* make: run goimports only for changed files
Applying goimports to all existing files would create a lot of problems with cherry-picking changes between different branches used for development. To avoid this it was decided to only run goimports on changed files to fix formatting gradually.

This commit changes background merge algorithm, so it becomes compatible with Windows file semantics.
The previous algorithm for background merge:
1. Merge source parts into a destination part inside tmp directory.
2. Create a file in txn directory with instructions on how to atomically
swap source parts with the destination part.
3. Perform instructions from the file.
4. Delete the file with instructions.
This algorithm guarantees that either source parts or destination part
is visible in the partition after unclean shutdown at any step above,
since the remaining files with instructions is replayed on the next restart,
after that the remaining contents of the tmp directory is deleted.
Unfortunately this algorithm doesn't work under Windows because
it disallows removing and moving files, which are in use.
So the new algorithm for background merge has been implemented:
1. Merge source parts into a destination part inside the partition directory itself.
E.g. now the partition directory may contain both complete and incomplete parts.
2. Atomically update the parts.json file with the new list of parts after the merge,
e.g. remove the source parts from the list and add the destination part to the list
before storing it to parts.json file.
3. Remove the source parts from disk when they are no longer used.
This algorithm guarantees that either source parts or destination part
is visible in the partition after unclean shutdown at any step above,
since incomplete partitions from step 1 or old source parts from step 3 are removed
on the next startup by inspecting parts.json file.
This algorithm should work under Windows, since it doesn't remove or move files in use.
This algorithm has also the following benefits:
- It should work better for NFS.
- It fits object storage semantics.
The new algorithm changes data storage format, so it is impossible to downgrade
to the previous versions of VictoriaMetrics after upgrading to this algorithm.
