Main 'pinger'
1. Requests domains
- if domain responded - keep status code
- if no response for timeout - keep Timeout status code
- if unreachable (ConnectionError or so) - keep 523 status code
(same logic as go implementation)

- obtains all scrape coro results from asyncio tasks
- saves ping results to ScrapeResult table
- updates 'is_resolved' field in DomainAlerts table, in case
error domain`s status code was changed to 200
- returns domains with non-200 status code code

- gets recently alerted domains (those that must not be alerted again)
and does not include them for alerting
- calls alerting for left domains
- updates DomainAlerts table:
if website was not alerted -> adds new record
if website was alerted before -> updates alert time and is_resolved marker

Scanner logic:
1. Scrapes domains and obtains ping results;
2. Manage ping results (e.g: saving to DB)
3. In case error domains found -> start re-pinging
Re-pinging:
- in min(ping_interval, 5 mins)
- flush alerts if needed
4. Sleep for ping_interval until next ping iteration
�< Nz8Those domains are unsuccessful: %s
