Allow overriding of buildah image with "kamel install" switches

[dtremblay]

Add a new kamel install switch to allow overriding the buildah image, e.g. "--buildah-image"

This switch would work in a similar fashion to "-base-image" and "-operator-image".

Whenever a new "kamel run" command gets used, the overriden buildah image would get used.

Unless I misunderstood the need, this should be fixed by #3558

I agree with you. I'll have to try this again to confirm. I'm closing the issue now.
