SkyPilot - Is there a way to create a new machine if existing machines with specific tags are busy?

You can achieve this by using the Python API and implementing status checks.
Determine the criteria for a machine to be considered 'busy', whether it's based on running jobs or other factors.
Utilize the API to check the status of existing machines with specific tags and their workload.
Based on the status, decide whether to create a new machine or reuse an existing one.
Implement logic to handle the creation of new machines based on the defined criteria.
