GCRules (Google Cloud Bigtable Parent 2.27.2 API)

```
@BetaApi
public final class GCRules
extends Object
```
Wraps GcRule protocol buffer object and exposes a friendly API.
Note: Garbage collection executes opportunistically in the background, and so it's possible for reads to return a cell even if it matches the active GC expression for its family. Please use appropriate filters in your reads to exclude cells which are eligible for garbage collection.
