Maddy/prompt password when different (#4537)

* Prompt for password once when the sql instance password doesn't work for hdfs. If the user provides the correct password, connect and continue, else show Unauthorized  node.

* Removed the hardcoded bad password

* Added check for empty folder scenarios

* Added ErrorStatusCode as property of TreeNode. Checking for the error code instead of the error string to avoid localization issues

* type fixed

* implemented hasExpansionError
