The purpose of this issue is to implement the setup command, which will acquire a lock on the server to prevent concurrent operations and then proceed with the installation of Docker. This command will require root access via SSH to execute the necessary steps for Docker installation.

Acceptance Criteria:

• Develop a server lock mechanism to acquire and release locks for exclusive access to the server.
• Implement error handling to handle scenarios where the server lock cannot be acquired, providing informative messages for troubleshooting.
• The "setup" command successfully detects the presence of Docker on the server.
• If Docker is not installed, the command installs Docker using the appropriate package manager via SSH.
• The command provides clear feedback and error messages when encountering issues during installation.
• Release the server lock upon completion or in case of any errors during the installation process.

Note: This implementation requires careful handling of root access and SSH connections for security purposes.
