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.

d8b46908db new feature: debug relabeling (#1344) 
* new feature: relabel logging

Use scrape_configs[x].relabel_debug = true to log metric names inkl.
labels before and after relabeling. After relabeling related metrics
get dropped, i.e. not submitted to servers.

* vminsert wants relabel logging, too.

1c09e71f5b app/vminsert: add -disableRerouting command-line flag for disabling re-routing if some vmstorage nodes have lower performance than the others 
Refactor the rerouting mechanism and make it more resilient to cases when some of vmstorage nodes are temporarily unavailable.

Reduce the probability of rerouting storm.
