Fix DTS resource group default name and auto-refresh after deletion (#4971)

- Set relatedNameTask in SchedulerNamingStep so ResourceGroupListStep
  pre-populates the default resource group name (#4967)
- Add azureResourceGroups.refresh command after scheduler deletion to
  auto-remove deleted items from tree view (#4968)
- Add azureResourceGroups.refresh command after task hub deletion to
  auto-remove deleted items from tree view (#4968)
