Vitali Lovich d602e9f98c fix: make cloud features optional (#2567) (#2568)
This shrinks the size of a local embedded build that can disable all the
default features. When combined with
https://github.com/lancedb/lance/pull/4362 and the dependencies are
updated to point to the fix, this resolves #2567 fully.

Verified by patching the workspace to redirect to my clone of lance with
the PR applied.
```
cargo tree -p lancedb -e no-build -e no-dev --no-default-features -i aws-config | less
```

The reason that lance itself needs to change too is that many
dependencies within that project depend on lance-io/default and lancedb
depends on them which transitively ends up enabling the cloud
regardless. The PR in lance removes the dependency on lance-io/default
from all sibling crates.

LanceDB Java SDK

Configuration and Initialization

LanceDB Cloud

For LanceDB Cloud, use the simplified builder API:

import com.lancedb.lance.namespace.LanceRestNamespace;

// If your DB url is db://example-db, then your database here is example-db
LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
    .apiKey("your_lancedb_cloud_api_key")
    .database("your_database_name")
    .build();

LanceDB Enterprise

For Enterprise deployments, use your VPC endpoint:

LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
    .apiKey("your_lancedb_enterprise_api_key")
    .database("your-top-dir") // Your top level folder under your cloud bucket, e.g. s3://your-bucket/your-top-dir/
    .hostOverride("http://<vpc_endpoint_dns_name>:80")
    .build();

Development

Build:

./mvnw install
