Update default master vcpu to 8 to support ICP 3.1

[hassenius]

As of ICP 3.1 PODs have been more appropriately scoped with resource requests and limits. If minimum resource requirements as specified in https://www.ibm.com/support/knowledgecenter/SSBS6K_3.1.0/supported_system_config/hardware_reqs.html are not met, deployment will fail as PODs will not be scheduled

Here is the new configuration for ICP 3.1.1
