Allow using of latest cpuv1 image for tenant

[zdzichu]

Is your feature request related to a problem? Please describe.
Some servers (like my k8s nodes) require a -cpuv1 container image; see minio/minio#18365
Operator's tenant console allows specifying the image. At the same time, the description hints If blank, then latest build will be used.
There's no way to get latest and cpuv1 at the same time. To get cpuv1 image, I need to provide exact RELEASE-x.y image.

Describe the solution you'd like
I would like to have latest and cpuv1 at the same time. I.e. I would like to be able to leave Image empty, to get the latest image, but at the same time I would like to specify that I need a cpuv1 image.
A checkbox would be enough, I think.

Describe alternatives you've considered
I don't see any alternatives.

Operator is not meant to be used on legacy hardware. Unfortunately we may not be able to support it.
