app/vmagent/remotewrite: skip sending empty block to downstream server () 
Occasionally, vmagent sends empty blocks to downstream servers. If a
downstream server returns an unexpected response, vmagent gets stuck in
a retry loop. While vmagent handles 400 and 409 errors, there are
various prometheus remote write implementations that return different
error codes. For example, vector returns a 422 error. To mitigate the
risk of vmagent getting stuck in a retry loop, it is advisable to skip
sending empty blocks to downstream servers.
