Today our docker image is based on Centos7 ,Since centos will be EOL in
2024 and no longer has stable release stream. let's move our docker image to be based on ubuntu 20.04
Based on the work done in https://github.com/scylladb/scylla/pull/8730,
let's build our docker image based on local packages using buildah
Closes#8849
The "ninja dist-server-tar" command is a full replacement for
"build_reloc.sh" script. We release engineering infrastructure has been
switched to ninja, so let's remove "build_reloc.sh" as obsolete.
In the section explaining how to build a docker image for a self-built
Scylla executable, we have a warning that even if you already built
Scylla, build_reloc.sh will re-run configure.py and rebuild the executable
with slightly different options.
The re-run of configure.py and ninja still happens (see issue #6547) but
we no longer pass *different* options to configure.py, so the rebuild
usually doesn't do anything and finishes in seconds, and the paragraph
warning about the rebuild is no longer relevant.

Clarify in README.md that the instructions there will build a Docker image
containing a Scylla executable downloaded from downloads.scylla.com - NOT
the one you built yourself. The image is also CentOS based - not Fedora-based
as claimed.
In addition, a new dist/docker/redhat/README.md explains the somewhat
steps needed to actually build a Docker image with the Scylla executable
that you built. In the future, these steps should be automated (e.g.,
"ninja docker") but until then, let's at least document the process.
