AUTOSCALE-266: Refactor karpenter-operator and karpenter into v2 components

[maxcao13]

What this PR does / why we need it:

This PR refactors the karpenter deployment and assets which are managed by the karpenter
operator to CPOv2. This removes the ability to pass in the karpenter aws image as an argument
to the karpenter-operator deployment, since we can directly get the karpenter aws image from
the payload image itself from within the karpenter-operator releaseImage lookup code. This
commit also removes the deprecated karpenter code.

What this PR does / why we need it:
This PR refactors the karpenter-operator and karpenter into CPOv2 components.

As part of this PR, one of the commits allows the hcp_controller to now manage and reconcile the karpenter deployment instead of the karpenter-operator. This is needed because in order to use CPOv2, we need to pass in a cpoContext, and it is non-trivial to create a new cpoContext specially for the karpenter-operator container.

This is probably no longer WIP, thanks for the review Mulham. +1

/test e2e-aws-techpreview

The core tests are timing out, I think we need to up some of the timeouts on them in our karpenter fork. After changing it and running it locally, it seems to pass after increasing the timeouts.
