Use job to install HyperShift operator

[philipwu08]

Signed-off-by: Philip Wu phwu@redhat.com

Description of the change(s):

• A job is used to install the HyperShift operator. This container created from the job uses the HyperShift operator image specified in the imagestream, or the hypershift-override-images configmap if it exists. By using the HyperShift CLI from the target HyperShift operator image to install the HyperShift operator, all resources, including the CRDs, are upgraded to the level of the target HyperShift operator image.

Why do we need this PR:

• The previous implementation uses the templates output from HyperShift render function to upgrade the HyperShift operator. The resource templates, including CRDs, are specific to the version of HyperShift bundled with the HyperShift agent addon. As a result, there may be a mismatch between the HyperShift resources from the render function, and the image of the upgraded HyperShift operator.
