43c39dc36c 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.

The v0.1.0 points to the last verified changes made by me.
I'm afraid that releases after v0.1.0 may contain completely broken changes like

83aca79137 lib/storage: recover when metricID->metricName entry is missing in the inverted index after unclean shutdown 
Newly added index entries can be missing after unclean shutdown, since they didn't flush to persistent storage yet.
Log about this and delete the corresponding metricID, so it could be re-created next time.

app/vmalert: initial remote-write support for alerts state persistence. (#442) 
* app/vmalert: initial remote-write support for alerts state persistence.

If `remotewrite.url` flag is set, vmalert will send alerts state  via remote-write protocol to remote storage. The sending is asynchronous to avoid blocking calls in rules evaluation loop.

* app/vmalert: merge with master

* app/vmalert: write both `instant` and `for` alerts timeseries states in remote storage.

b4afe562c1 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.

d7c1ff8b0c lib/storage: improve deduplication algorithm 
Now it leaves only the first data point on each `-dedup.minScrapeInterval` interval.

Previously it may leave two data points on the interval. This could lead to unexpected results
for `histogram_quantile(phi, sum(rate(buckets)) by (le))` query.

    more than N time series found on the time range [...]; either increase -search.maxUniqueTimeseries or shrink the time range
