When `--vm-native-step-interval` is specified, explore phase will be executed
within specified intervals. Discovered metric names will be associated with
time intervals at which they were discovered. This suppose to reduce number
of requests vmctl makes per metric name since it will skip time intervals
when metric name didn't exist.
This should also reduce probability of exceeding complexity limits
for number of selected series in one request during explore phase.

Before, retries happened only on writes into a network connection
between source and destination. But errors returned by server after
all the data was transmitted were logged, but not retried.

app/vmctl: don't interrupt migration process if tenant has no data

Binary export API protocol can be disabled via `-vm-native-disable-binary-protocol` cmd-line flag when migrating data from VictoriaMetrics. Disabling binary protocol
can be useful for deduplication of the exported data before ingestion.
For this, deduplication need to be configured at `-vm-native-src-addr` side
and `-vm-native-disable-binary-protocol` should be set on vmctl side.

app/vmctl: vm-native - split migration on per-metric basis
`vm-native` mode now splits the migration process on per-metric basis.
This allows to migrate metrics one-by-one according to the specified filter.
This change allows to retry export/import requests for a specific metric and provides a better
understanding of the migration progress.

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.

vmctl: fix vmctl blocking on process interrupt
This change prevents vmctl from indefinite blocking on
receiving the interrupt signal. The update touches all
import modes and suppose to improve tool reliability.

add progress bars to the VM importer
The new progress bars supposed to display the processing speed per each
VM importer worker. This info should help to identify if there is a bottleneck
on the VM side during the import process, without waiting for its finish.
The new progress bars can be disabled by passing `vm-disable-progress-bar` flag.
Plotting multiple progress bars requires using experimental progress bar pool
from github.com/cheggaaa/pb/v3. Switch to progress bar pool required changes
in all import modes.
The openTSDB mode wasn't changed due to its implementation, which implies individual progress
bars per each series. Because of this, using the pool wasn't possible.

The new flag `vm-rate-limit` defines data transfer speed limit
in bytes per second. Rate limiting is not applied if flag is omitted.

It is better developing vmctl tool in VictoriaMetrics repository, so it could be released
together with the rest of vmutils tools such as vmalert, vmagent, vmbackup, vmrestore and vmauth.
