Description: 
If there is invalid definition/json in alert definition then Upgrade would fail 
with below exception. there is no way to determine which alert is causing the 
issue here.

its not clear how this alert definition gets corrupted but we have seen this 
with 3 to 4 customers already - printing the alert definition name would he 
helpful in support point of view to determine the root cause.. other wise it is 
very difficult to find it out - had a give a dev patch to customers to find it 
out.
