"Missing credential" error is not user-friendly (connecting to TypeDB Cluster without correct args)

[alexjpwalker]

Problem to Solve

When you use ./typedb console in Cluster, it says:

[CLS06] Server Error: Missing credential.

Proposed Solution

Although it's fairly clear what the problem is, the message could definitely be nicer. For instance, it could say that the CLI arguments --username and --password are required.

To be specific, there are two other things that makes it even worse.

One, the stack trace is printed even though there's no need to:

./typedb console --cluster=typedb-cluster-1:1729 --username=admin --password
Password: <an-incorrect-password>

And two, Console will actually hang rather than terminating with error.
