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.

all: locate throttled loggers via logger.WithThrottler() only once and then use them 
This reduces the contention on logThrottlerRegistryMu mutex when logger.WithThrottler()
is called frequently from concurrent goroutines.

a1b298a842 app/vminsert/netstorage: disable rerouting by default 
Production clusters work more stable with the disabled rerouting during rolling restarts and/or
during spikes in time series churn rate. So it would be better disabling the rerouting by default.

The re-routing can be enabled by passing `-disableRerouting=false` command-line flag to `vminsert` nodes.

0d067eb112 app/vminsert/netstorage: tune re-routing algorithm 
Do not re-route data to unavailable storage node. Send it to the remaining storage nodes instead
even if they cannot keep up with the load. This should spread the load more evenly among available
storage nodes.

ffa6581c46 app/vminsert: refresh the list of healthy storage nodes only if the the row cannot be sent to destination storage node

a586b8b6d4 app/vminsert/netstorage: do not re-route every time series to more than two vmstorage nodes when certain vmstorage nodes are temporarily slower than the rest of them 
Previously vminsert may spread data for a single time series across all the available vmstorage nodes
when vmstorage nodes couldn't handle the given ingestion rate. This could lead to increased usage
of CPU and memory on every vmstorage node, since every vmstorage node had to register all the time
series seen in the cluster. Now a time series may spread to maximum two vmstorage nodes under heavy load.
Every time series is routed to a single vmstorage node under normal load.
