app/vminsert: fixes readonly check ( #4892 )
...
* app/vminsert: fixes readonly check
previously vminsert doesn't check readOnly state for vmstorage, since check was never performed for nil buffer
In this case every 30 second storage node loss readonly state and received some data.
It caused re-routing and possible slow down for ingestion

This eliminates the need in .(*T) casting for results obtained from Load()
Leave atomic.Value for map, since atomic.Pointer[map[...]...] makes double pointer to map,
because map is already a pointer type.

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.

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.
