[connectedk8s] Escaping newlines in python strings produces weird spaces in cli error messages

[logangeorge01]

Describe the bug

Escaping new lines in python strings in connectedk8s cli extension is producing large spaces in error messages. One of our test cases relies on matching the error messages and the space is breaking us.

One of likely many occurences is in the following file at line 398.
https://github.com/Azure/azure-cli-extensions/blob/83a18a57c034f2e350e2c53bc46afc1909d3cfc2/src/connectedk8s/azext_connectedk8s/custom.py

Related command

Running az connectedk8s create pointing to a k8s cluster that's already been connected. This issue likely appears many times in connectedk8s output, and maybe other extensions if they are following a similar pattern trying to shorten code line length.

Errors

The kubernetes cluster you are trying to onboard is already onboarded to                 the resource group 'rg' with resource name                     'cluster'.

Issue script & Debug output

Not necessary

Expected behavior

Don't want to see the extra space in output
