Why are we doing this work

From Epic:

For US Government customers to use GitLab's secure analyzers, they need to have them built on a UBI-based image.

Non-functional requirements

• [-] Feature flag:
• [-] Performance:
• Testing: extend integration tests to test both original Dockerfile and UBI-based

Documentation is covered by https://gitlab.com/gitlab-org/gitlab/-/issues/354796+

Implementation plan

• backend use go-fips image to build binaries (from https://gitlab.com/gitlab-org/gitlab-runner/-/tree/main/dockerfiles/fips or based on https://gitlab.com/gitlab-org/gitlab/-/issues/354997)
• backend use ubi8 image as a main image for Dockerfile
• backend prepare separate https://gitlab.com/gitlab-org/security-products/analyzers/gemnasium-maven/-/blob/master/config/install.sh script to work with ubi8 image,
• backend in case of any required dependencies, add:

  RUN yum -y -q update --disableplugin=subscription-manager && \
      yum -y -q upgrade --disableplugin=subscription-manager && \
      yum -y -q install --disableplugin=subscription-manager git && \
      yum -y clean all --enablerepo='*'

• backend move certificates to /etc/pki/: (see #354993 (comment 904954897))
