OnDuplicate uses ConstantsTrait

Strategies accepted by the `onDuplicate` query parameter of the ArangoDB bulk import endpoint (`POST /_api/import?collection={name}`).

The value tells the server how to handle a row whose _key collides with an existing document:

ERROR — refuse the row and report it in the errors count (default behaviour).
UPDATE — patch the existing document with the supplied fields.
REPLACE — overwrite the existing document with the supplied payload (PUT semantics — fields absent from the row are dropped).
IGNORE — silently skip the row and bump the ignored count.

ERROR : string = 'error': Refuse the duplicate row and bump the `errors` count.
IGNORE : string = 'ignore': Silently skip the duplicate row and bump the `ignored` count.
REPLACE : string = 'replace': Overwrite the existing document with the supplied payload.
UPDATE : string = 'update': Patch the existing document with the supplied fields.

Refuse the duplicate row and bump the `errors` count.
