Default onError for invoked actors

[crishoj]

I find myself repeating onError attributes in machines with lots of invoked actors.

Would it be crazy to allow a "default" onError to be specified in StateNodeConfig?

createMachine({
  initial: 'running',
  states: {
    running: {
      onError: 'failed',  // 👈 This is what I would like to do
      states: {
        idle: {
          invoke: { src: 'someService', onDone: 'processing' }
        },
        processing: {
          invoke: { src: 'someOtherService', onDone: 'success' }
        },
        success: {}
      }
    },
    failed: {
      // From here we could resume to a history state 
    }
  }
})

Invoked actors within the running state could use the default onError transition, if they don't specify their own onError transition.

This is a good idea. Might not really be type-safe, since it's hard to predict which invokes it's for, and ideally this can be used for any error that happens in the state.

I like this idea, and I would also like for onError to catch all errors that happens, not just errors that happens in the invoked actor. ie, catch synchronous errors from actions and inputs as well.
