b6d88bac04 vendor: use github.com/VictoriaMetrics/fasthttp instead of github.com/fasthttp/fasthttp
The upstream fasthttp may contain issues like 996610f021 ,
plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.

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.

e933cbac16 lib/storage: postpone reading data from blocks during search
This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.

This improves single-node VM performance on heavy queries by up to 2x.

to duplicate samples in time series.
