If this Epic is an RFE, please complete the following questions to the best of your ability:

Q1: Proposed title of this RFE

SMT levels for Power during openshift-install

Q2: What is the nature and description of the RFE?

openshift-install currently takes an install-config.yaml parameter for `hyperthreading`. On Power it is not a boolean. Threading can be set to 1/2/4/8.

Q3: Why does the customer need this? (List the business requirements here)

Some workloads do not scale well with the default level of threads on Power (8). If the workload works better with SMT=4, customer would prefer to setup the parameter during install.

Q4: List any affected packages or components
