Changelog:
```

- [JSON-API] make key_hash indexes non-unique, this fixes a bug where a duplicate key conflict was raised on the query store when the same contract was being witnessed twice by two separate parties

* [Trigger Service] Enable the new `tablePrefix` setting in the `--jdbc`
  flag to add a prefix to all tables used by the trigger service to
  avoid collisions with other components using the same db-schema.
* [Trigger Service] Enable the new ``--allow-existing-schema`` flag to
  initialize the trigger service on a database with a pre-existing
  schema.

- [Daml Assistant] Add support for `--max-inbound-message-size` flag to the Ledger Export tool.

Add cons, find, delete and deleteBy functions to NonEmpty module.
