CLOUDSTACK-8300: Set indexes on event table
When there are many events in the cloud.event table, the UI throws an SQL
exception and the management server spikes at 100% CPU for minutes. That causes
other API calls to fail with 530 errors.
It seems an index on the 'archived' field is missing (since it is used in
the WHERE clause).
We have 1.4M events in the table:
`select count(*) from event;`
1497838
This PR adds the index to the `archived` field and the `state` field.
