The error shown when adding a node to cluster while giving wrong credentials is redundant

Repro steps:
1. Setup a node (Node1) with Administrator:password as the credentials.
2. Setup another node (Node2) with Administrator:asdasd as the credentials
3. Now add Node2 into the Node1 cluster. Provide wrong credentials (not Administrator:password) while adding the node.

The error message shown to the user is redundant. Only the first line of the error is enough to convey the message that the username and password given is wrong. The information that http status returned 401 from the rest call is redundant.
