Today our container is based on ubuntu:22.04, we need to build another container based on Ubuntu Pro for FIPS support (currently the latest one is 20.04) The default docker build process doesn't change, if FIPS is required I have added `--type pro` to build a supported container. To enable FIPS there is a need to attach an Ubuntu Pro subscription (it will be done as part of https://github.com/scylladb/scylla-pkg/issues/4186) Closes scylladb/scylladb#21974
