Ability to view by batch / search by batch

When you use yourTask.batchTrigger() or yourTask.batchTriggerAndWait() a batch is created. You get a batch handle back with an id.

At the moment there is no way get all the runs from that batch in the SDK or in the dashboard.

We should:

1. Add the ability to filter by batchId in the dashboard runs list
2. Add the ability to filter by batchId in runs.list()
