@infernus01 - Right now we do not want to enable the worker count to be user configurable. Is there any specific reason we intend to have this change?

It seems to me like we have 'if' checks for configmap values and then getting values from env variables. It looked odd to me, but there might be some reason behind this. I'll reopen this if found something not good.
