[flytekit-java] Support WorkflowMetadata and WorkflowMetadataDefaults

[kanterov]

Why would this be helpful to the Flyte community From flyteidl:

// This is workflow layer metadata. These settings are only applicable to the workflow as a whole, and do not
// percolate down to child entities (like tasks) launched by the workflow.
message WorkflowMetadata {
    // Indicates the runtime priority of workflow executions. 
    QualityOfService quality_of_service = 1;

    // Failure Handling Strategy
    enum OnFailurePolicy {
        // FAIL_IMMEDIATELY instructs the system to fail as soon as a node fails in the workflow. It'll automatically
        // abort all currently running nodes and clean up resources before finally marking the workflow executions as
        // failed.
        FAIL_IMMEDIATELY = 0;

        // FAIL_AFTER_EXECUTABLE_NODES_COMPLETE instructs the system to make as much progress as it can. The system will
        // not alter the dependencies of the execution graph so any node that depend on the failed node will not be run.
        // Other nodes that will be executed to completion before cleaning up resources and marking the workflow
        // execution as failed.
        FAIL_AFTER_EXECUTABLE_NODES_COMPLETE = 1;
    }

    // Defines how the system should behave when a failure is detected in the workflow execution.
    OnFailurePolicy on_failure = 2;
}

// The difference between these settings and the WorkflowMetadata ones is that these are meant to be passed down to
// a workflow's underlying entities (like tasks). For instance, 'interruptible' has no meaning at the workflow layer, it
// is only relevant when a task executes. The settings here are the defaults that are passed to all nodes
// unless explicitly overridden at the node layer.
// If you are adding a setting that applies to both the Workflow itself, and everything underneath it, it should be
// added to both this object and the WorkflowMetadata object above.
message WorkflowMetadataDefaults {
    // Whether child nodes of the workflow are interruptible.
    bool interruptible = 1;
}
