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.

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.
