Refactor Cypress test pod build

[meissadia]

• Takes a really long time
• Each build ends results in multiple GBs worth of new layers
• I think we're building a full CentOS pod from scratch
• Can we build on the Cypress Docker images? I think security was the previous blocker there. Has anything changed?

UBI8 is missing Cypress dependencies:

# No match for argument: xorg-x11-server-Xvfb
# No match for argument: gtk2-devel
# No match for argument: gtk3-devel
# No match for argument: libnotify-devel

Options to explore:

• Adding software to a UBI container
• https://stackoverflow.com/questions/64919789/how-to-install-xvfb-on-rh8
• Check with DevOps team to see if we have a RHEL subscription, then we could login to that? Or build on a machine that is logged into that? I'm not sure how this piece works...

• Got additional dependency repos configured in the UBI8 version!
• Able to avoid explicit versions for the majority of the libraries
• Smoke testing (ran Tools specs) looks good
• Going to request another vulnerability scan
