```csharp
public abstract Task<object[]> SendControlCommandToProvider<T>(string providerName, int command, object arg = null)
```

Execute a control command on the specified providers on all silos in the cluster. Commands are sent to all known providers on each silo which match both the `providerTypeFullName` AND `providerName` parameters.

### Parameters
