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.

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.
