The IsAlive flag for read models is false although read model is live (no any errors)

[pavsenin]

Describe the bug
Regarding the current specification, if the IsAlive flag is false we retry getting its value within 30-60 seconds. If it is still false we conclude that the read model is dead. If I understand correctly the monitoring-prod lambda works in such manner but we get a lot of false positives in our channel https://teams.microsoft.com/l/channel/19%3a9ccf665054a14c9fbc389ac08dbfaea1%40thread.skype/Dashboard%2520Monitoring?groupId=c3abb0f3-231c-4d87-b5a3-44925dc1d075&tenantId=e4d60396-9352-4ae8-b84c-e69244584fa4

Expected behavior
We do not get false positives in the Dashboard Monitoring teams channel.
