* 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.

The stored backups would help to identify docs corruption
but aren't needed for commiting. So `.tmp` backup files
are also git-ignored.

The `docs-sync` command was updated to modify images path
for assets in `docs/` folder. The change allows to refer images from `docs`
without copying them to the root folder.

`go install` is the preferred way for installing go binaries starting
from the minimum supported Go version for VictoriaMetrics - Go1.18 -
see https://tip.golang.org/doc/go1.18#go-command
The automated push of release tags to Github require specifying the remote repository name
when doing `git push <remote-repo-name> v1.xx.y`.
The remote repository name can differ in different environments,
so it cannot be put into Makefile rule.
TODO: create a Makefile rule, which generates standard remote names for public
and private repositories in Git, so `git push` for release tags could be automated then.
The `-mod=vendor` is automatically set when there is a `vendor` directory
starting from Go1.14 - see https://go.dev/doc/go1.14#go-command
Since the minimum supported Go version for VictoriaMetrics is Go1.17,
then the `-mod=vendor` option is no longer needed.
* deployment/docker/Makefile: added docker-scan
docker-scan based on native 'docker scan' function that use snyk.io, see https://docs.docker.com/engine/scan/
* set to call 'docker-scan after release binaries but before publishing
