* vmalert: speed up state restore procedure on start Alerts state restore procedure has been changed to become asynchronous. It doesn't block groups start anymore which significantly improves vmalert's startup time. Instead, state restore is called by each group in their goroutines after the first rules evaluation. While previously state restore attempt was made for all loaded alerting rules, now it is called only for alerts which became active after the first evaluation. This reduces the amount of API calls to the configured remote read URL. This also means that `remoteRead.ignoreRestoreErrors` command-line flag becomes deprecated now and will have no effect if configured.
