* Added two settings values for declaring absolute cpu and memory
capacity that will be picked up by the capacity utility methods
* installer inventory variables for controlling the amount of cpu and
memory container requests/limits for the awx task containers
* Added fixed values for cpu and memory container requests for other
containers
* configmap uses the declared inventory variables to define the
capacity inputs that will be used by AWX to correspond to the same
inputs for requests/limits on the deployment.
