app/cluster: communicate node IDs when performing a handshake
Send a node ID of vmstorage as a part of vmselect and vminsert handshakes.
Use vmstorage node ID as an identifier for consistent hashing at vminsert.

Cluster native endpoints calculate vminsert and vmselect node IDs as a hash of all underlying storage node IDs, so that it will also remain consistent in case of address changes.

d962568e93 all: use %w instead of %s for wrapping errors in fmt.Errorf
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .
See https://blog.golang.org/go1.13-errors for details.

989d84cf3f app/{vminsert,vmstorage}: wait for ack from vmstorage after each packet sent to it from vminsert
This should protect from possible data loss when `vmstorage` is stopped while the packet is sent from `vminsert`.

This commit switches to new protocol between vminsert and vmstorage, which is incompatible
with the previous protocol. So it is required that both vminsert and vmstorage nodes are updated.
