[IntelliJ] Azure Blob container lost in storage container list when user restart the project

[t-rufang]

Repro steps:

1. Open run configuration dialog and open a Azure HDInsight Spark configuration
2. Choose Azure Blob as Job Upload Storage type
3. Fill the storage account and storage key, select one container from the container list
4. Save the configuration
5. Restart the project, open run configuration dialog and open the Azure HDInsight Spark configuration you modified defore. We can find the container list has only one container (the one we selected before). However, we expect to see the container list so user can choose one from them

• Workaround for this issue:
  The container list should refresh itself when focus lost on storage account or storage key field.

• Feature request:
  Add a refresh button just as the cluster refresh button. When user click the button, we should refresh the container list.
