Events are not created when alert manager is unable to create the alert due to error

[phanipadala]

Is this a BUG REPORT or FEATURE REQUEST?:
Bug

What happened:
When there is an invalid value passed as param [Eg: severity value as "warning" instead of "warn"] , controller will not create wavefront alert and show error in controller logs . Currently we dont see events generated for the error.

What you expected to happen:
We should see error message in the events when we use kubectl kubectl get events .

How to reproduce it (as minimally and precisely as possible):
In Alerts config , pass invalid severity value as "warning" and try to apply it.

Anything else we need to know?:

Environment:

• alert-manager version
• Kubernetes version :

$ kubectl version -o yaml

Other debugging information (if applicable):

- controller logs:

$ kubectl logs

i was checking the logs and looks like we need patch access as well for events.

'events "fluentd-errors.16a8297caa6d370d" is forbidden: User "system:serviceaccount:alert-manager-system:alert-manager-controller-manager" cannot patch resource "events" in API group "" in the namespace "dev-iksmanager-usw2-ldev"' (will not retry!)
