This change ensures that chunk replicas are created on remote (datanode) servers whenever a chunk is created in a local distributed hypertable. Remote chunks are created using the `create_chunk()` function, which has been slightly refactored to allow specifying an explicit chunk table name. The one making the remote call also records the resulting remote chunk IDs in its `chunk_server` mappings table. Since remote command invokation without super-user permissions requires password authentication, the test configuration files have been updated to require password authentication for a cluster test user that is used in tests.
