Upgrade HerdDB to 0.16, Pulsar Client to 2.5.2, add demo config for diskless-cluster mode (#303)

### Motivation

Since HerdDB 0.16 you can store all of the data on BookKeeper, this is called "diskless-cluster" mode.
So you will be able to run PulsarManager + HerdDB on a stateless pod, all of the data will be stored on the same BK+ZK cluster as your Pulsar installation. 

### Modifications

- Upgrade HerdDB to 0.16.1.
- Upgrade Apache Pulsar Admin Client to 2.5.2 (that officially supports BK 4.10)
- Use pulsar-client-admin-original instead of pulsar-client-admin, because pulsar-client-admin contains a shaded version of CirceChecksum library from BK that is not compatibile with BK 4.10, needed by HerdDB in order to run in diskless-cluster  mode.
- Configure gradle to put application.properties inside pulsar-manager.tar, this way it is super easy to change the configuration of pulsar-manager backend without recompiling the package (no need to use Gradle for System administrator)
- Add an example JDBC URI to boot HerdDB in diskless-cluster mode


### Verifying this change

- [ ] Make sure that the change passes the `./gradlew build` checks.
