Add configuration for optional CPU request on build pod

[bluek1te]

Add ability to configure CPU request on build pod - We have cluster restrictions that require us to affix a cpu request before spawning pods so this would help us immensely.

Unfortunately this won't work, because the "build pod" doesn't build the image directly, it calls out to an external Docker or Podman build daemon.

We just need a CPU resource attribute to be affixed to the build pod. Even if it calls out to an external docker daemon, the "build pod" still takes some amount of CPU to run. There are already configurations for memory requests/limits for this specific pod, so I don't see why this would be any different.
