lib/storage: skip blocks outside the configured retention during search
Blocks outside the configured retention are eventually deleted during background merge.
But such blocks may reside in the storage for long time until background merge.
Previously VictoriaMetrics could spend additional CPU time on processing such blocks
during search queries. Now these blocks are skipped.

all: subsitute ioutil.ReadAll with io.ReadAll
ioutil.ReadAll is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil
VictoriaMetrics requires at least Go1.18, so it is OK to switch from ioutil.ReadAll to io.ReadAll.

all: use os.ReadDir instead of ioutil.ReadDir
The ioutil.ReadDir is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil

all: use os.{Read|Write}File instead of ioutil.{Read|Write}File
The ioutil.{Read|Write}File is deprecated since Go1.16 -
see https://tip.golang.org/doc/go1.16#ioutil

VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage
from source code.

app/vmauth: follow-up for 13368bed18
* Document the ability to specify http or https urls in `-auth.config` at docs/CHANGELOG.md
* Move the ReadFileOrHTTP to lib/fs, so it can be re-used in other places where a file
  should be read from the given path. For example, in `-promscrape.config` at `vmagent`.

89e1a45cdb lib/fs: concurrently remove up to 1024 blocked NFS directories
Previously the blocked directories were removed sequentially by a single goroutine.
This can be not enough for highly loaded VictoriaMetrics that accepts millions of sample per second,
when big number of LSM parts are created and removed at high rate.

d88fa5ebe4 Adds windows build (#1040)
* fixes windows compilation,
adds signal impl for windows,
adds free space usage for windows,
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/70
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1036

NOTE victoria metrics database still CANNOT work under windows system,
only vmagent is supported.
To completly port victoria metrics, you have to fix issues with separators,
parsing and posix file removall

* rollback separator

* Adds windows setInformation api,
it must behave like unix, need to test it.
changes procutil

* check for invlaid param

* Fixes posix delete semantic

* refactored a bit

* fixes openbsd build

* removed windows api call

* Fixes code after windows add

b9616c017f lib/{mergeset,storage}: remove transaction files only after the mentioned dirs are really removed
This should fix the issue on NFS when incompletely removed dirs may be left
after unclean shutdown (OOM, kill -9, hard reset, etc.), while the corresponding transaction
files are already removed.

5f52eb7653 lib/fs: do not postpone directory removal on NFS error
Continue trying to remove NFS directory on temporary errors for up to a minute.

The previous async removal process breaks in the following case during VictoriaMetrics start

- VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them.
- The transaction instructs removing old directories for parts, which were already merged into bigger part.
- VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors.
- VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished
  and finds directories, which should be removed, but weren't still removed due to NFS errors.
- VictoriaMetrics panics when it finds unexpected empty directory.

82bfe818d0 lib/fs: try harder with directory removal on NFS in the event of temporary lock
Do not give up after 11 attempts of directory removal on laggy NFS.

Add `vm_nfs_dir_remove_failed_attempts_total` metric for counting the number of failed attempts
on directory removal.

Log failed attempts on directory removal after long sleep times.
