Changelog:
```
- [Engine] Fix contract ID freshness check when validating transaction
- [Integration Kit] new streaming query for contract state events
- [Integration Kit] indexing contract keys for consuming exercise events
- Add prometheus metrics as a cli option in the participant integration api
[daml build] A new flag `--access-token-file` is added for the `daml
build` command. It allows the specify the path to an access token to
authenticate against the ledger API. This is needed if the project
depends on a remote Daml package hosted on such a ledger. Alternatively,
the path to the token can also be specified in the `daml.yaml` project
file under the `ledger.access-token-file` field.
[daml packages] A new `daml packages list` command has been added to
list packages deployed on a remote Daml ledger.
- Daml: (Early access) add support for BigNumeric
- [HTTP JSON API] Range queries within variant data would not return matching
  data when using the PostgreSQL backend with JSON API; this is fixed.
  See `issue #9321 <https://github.com/digital-asset/daml/pull/9321>`__.
