Optional. A list of alerting policy field names. If this
field is not empty, each listed field in the existing
alerting policy is set to the value of the corresponding
field in the supplied policy (alert_policy), or to the
field's default value if the field is not in the supplied
alerting policy. Fields not listed retain their previous

user_label.nameofkey, enabled, conditions,
If this field is empty, then the supplied alerting policy
replaces the existing policy. It is the same as deleting the
existing policy and adding the supplied policy, except for
- The new policy will have the same [ALERT_POLICY_ID]
as the former policy. This gives you continuity with the
former policy in your notifications and incidents.
- Conditions in the new policy will keep their former
[CONDITION_ID] if the supplied condition includes the
name field with that [CONDITION_ID]. If the
supplied condition omits the name field, then a new
[CONDITION_ID] is created.
Required. The updated alerting policy or the updated values
for the fields listed in update_mask. If update_mask
is not empty, any fields in this policy that are not in
update_mask are ignored.
