WHAT

The default machine pool will handle cluster wide components e.g operators (kas-fleet-shard, strimzi, observability, logging) and the ingress controllers. 

It has to be correct sized to handle these components and it must be autoscaled to only consume the resources that it needs.

the scaling configurations limits are: minimum of 6 nodes and maximum of 18 nodes. (This has been proposed in the epic brief)

WHY

So that the default machine pool is correct sized to handle the cluster wide components and it is also scaled

HOW

Update https://github.com/bf2fc6cc711aee1a0c2a/kas-fleet-manager/blob/dcc057d99f90d7942a5b74aa36c30df7dc472fdd/internal/kafka/internal/clusters/cluster_builder.go#L79 to create an autoscaled default machine pool with the 6 nodes minimum and 18 nodes maximum. 

DONE

Include the following where applicable:

• Autoscaled default machine pool created
