[BUG] Spinner animation blocks the input prompt from Diagnostic tool

[parthosa]

Diagnostic tool requires a user prompt to confirm that it will collect sensitive information from the cluster. This prompt interferes with the spinner animation in non-verbose mode and does not show up correctly.

Output:

psarthi@work:~/sample_dir$ spark_rapids_user_tools dataproc diagnostic --cluster test_cluster
Processing...⣷so you want to continue (yes/no):
Processing...⣻
Processing Completed!
psarthi@work:~/sample_dir$

I've noticed that I lose my cursor on the command line after running a tools command since the Processing... change. I can regain it by running reset, but it would be good to make sure this fix applies for that use case as well.

Thanks @mattahrens. I will add this fix in this change.
