Check cg-pipeline CPUs used

📝 Describe the Issue

The cg-pipeline task doesnt take CPUs as input. 4 are passed in. Does it use all available?

Pass in the set number of CPUs in the task.
Run the task and figure out how much RAM is normally used (/usr/bin/time -v cmd).
Does it really need 8GB?
Does it require a 100GB local disk?
How much processing time is used and calculate the utilisation of the CPUs? If its not making use of all 4, adjust the task to use less.

This task is very short. Make it preemptible (spot) so that we can access lower pricing. Google give 30 seconds notice before killing it, so we shouldn't notice any difference.

In the runtime section of the task set:

maxRetries: 3
preemptible: 1
