fix: Reconsider CLI defaults #392

[harsh082ip]

As discussed in issue-392, I have implemented the following fixes:

Set the default node size to g4s.kube.xsmall Set the default number of nodes to 2 Ensured firewall rules are correctly applied during cluster creation However, I was unable to make the OS selection deterministic. The API documentation does not seem to provide any guidance on this. Could you please advise on how to achieve this?

Please review and let me know if any further changes are needed.
