Steps to reproduce:
setup operations disabling discovery for items with connected trigger severity override does not work, only no_discover on matched items is set

without NO_DISCOVER operation triggers are managed by the override rule

overrides:

• name: 'Disable backups monitoring for matched dbs'
  step: '1'
  filter:
  conditions:
• macro: ' {#DBNAME}

  '
  value: '{$PG.BACKUP.FILTER.DBNAME}'
  formulaid: A
  operations:

• operationobject: ITEM_PROTOTYPE
  operator: LIKE
  value: recent
  discover: NO_DISCOVER
• operationobject: TRIGGER_PROTOTYPE
  operator: LIKE
  value: recent
  severity: NOT_CLASSIFIED

Expected result:
severity override was added to operations because 'disable not discovered' is not set to 'immediately'
matched items should not be discovered and deleted according to 'not discovered delete policy'
matched triggers should change severity immediately until deleted by the delete policy
