create prepare_one_node_cluster command

[wanghanchengchn]

Summary

To better support the deployment and management of single-node Kubernetes clusters, I have created a new command prepare_one_node_cluster. Previously, the create_one_node_cluster command was responsible for both preparing the single-node environment and setting up the master node. Now, I have added a new command called prepare_one_node_cluster. With this new command, users can first prepare the single-node environment, and then manually run setup_master_node to set up the master node when needed. This increased flexibility enables users to selectively execute the relevant steps based on their specific needs.

Implementation Notes :hammer_and_pick:

First, I have split the create_one_node_cluster command into two parts: preparing the single-node environment and setting up the master node. Note that I have only divided the previous create_one_node_cluster command into two functions, without affecting the functionality of the original create_one_node_cluster command.

Subsequently, I have created the prepare_one_node_cluster command, which only runs the first part of the create_one_node_cluster command, i.e., the part responsible for preparing the single-node environment. After running the prepare_one_node_cluster command, users can manually call the setup_master_node command when they need to.

Hi hancheng, please pass the unit test there

The reason why runner is failing is because we use create one node cluster on other function. https://github.com/vhive-serverless/vHive/blob/cc526822194dc0b725cb6e520bf920b5aae44fb2/scripts/cloudlab/start_onenode_vhive_cluster.go#L121

Please add setup master node there and re-run the checks.
