Spec down the default cluster EC2 instance type

Reduce the default EC2 instance type from a m4.10xlarge to:

* m4.large for the single-master recipe (95% saving on AWS bill)
* m4.xlarge for the master-slave recipe (90% saving on AWS bill)
* m4.2xlarge for the dual-master recipe (80% saving on AWS bill)

Also, reduce accordingly the default CPU and memory allocated to the Gerrit
instances to 1 vCPU and 6Gb respectively.
