New tickets are not logged in ServiceNow integration

New tickets are not logged in ServiceNow integration

Problem: New tickets are not logged in ServiceNow integration, even when new alerts are being created for the reported 
monitor (Issue persists in Applications Manager builds lower than 14670)

Solution:
Ensure that Log a Ticket action is configured for Critical, Warning and Clear severity. 
If there is no Action associated for Clear severity, Applications Manager will still maintain the initial ticket and update it, as it does not know whether the initial ticket was cleared or not.
