* Update docs/CHANGELOG.md

app/{vminsert,vmselect}/netstorage: allow calling Init()+MustStop() in a loop 
Previously netstorage.MustStop() call didn't free up all the resources,
so the subsequent call to nestorage.Init() would panic.

This allows writing tests, which call nestorage.Init() + nestorage.MustStop() in a loop.
