4f8a3af061 lib/protoparser/promremotewrite: synchronously process Prometheus remote_write requests
There is no reason in processing these requests asynchronously in the face of https://github.com/VictoriaMetrics/VictoriaMetrics/issues/896
Synchronous processing code is easier to read and understand than the previous async code

d5dddb0953 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.
