Associating multiple SSH key pairs with a cloud instance via CLI

What would you like to see added?

Currently, only one SSH key pair can be associated with a cloud instance during instance creation. This can make it difficult for users who need to access the same cloud instance from multiple systems using different SSH keys.

The instance must first be created and configured using a single SSH key pair. After the initial setup, additional authorized users can add their public SSH keys to the appropriate user's ~/.ssh/authorized_keys file. This allows access to the same instance using multiple SSH keys without sharing private keys. Appropriate file permissions and key management practices should be followed.
