Aliaksandr Valialkin	1f89278d88	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.

Aliaksandr Valialkin	9f94c295ab	all: use os.{Read|Write}File instead of ioutil.{Read|Write}File ...
