On the environment hard limit of coredump is set to zero, coredump test
script will fail since the system does not generate coredump.
To avoid such issue, set ulimit -c 0 before generating SEGV on the script.
Note that scylla-server.service can generate coredump even ulimit -c 0
because we set LimitCORE=infinity on its systemd unit file.

On Ubuntu 20.04 AMI, scylla_raid_setup --raiddev /dev/md0 causes
'/dev/md0 is already using' (issue #7627).
So we merged the patch to find free mdX (587b909).
However, look into /proc/mdstat of the AMI, it actually says no active md device available:
ubuntu@ip-10-0-0-43:~$ cat /proc/mdstat
Personalities :
unused devices: <none>
We currently decide mdX is used when os.path.exists('/sys/block/mdX/md/array_state') == True,
but according to kernel doc, the file may available even array is STOPPED:
clear
No devices, no size, no level
Writing is equivalent to STOP_ARRAY ioctl
https://www.kernel.org/doc/html/v4.15/admin-guide/md.html
So we should also check array_state != 'clear', not just array_state
existance.

Current fs.aio-max-nr value cpu_count() * 11026 is exact size of scylla
uses, if other apps on the environment also try to use aio, aio slot
will be run out.
So increase value +65536 for other apps.

On RAID prompt, we can type disk list something like this:
/dev/sda1,/dev/sdb1,/dev/sdc1,/dev/sdd1
However, if the list has spaces in the list, it doesn't work:
/dev/sda1, /dev/sdb1, /dev/sdc1, /dev/sdd1
Because the script mistakenly recognize the space part of a device path.
So we need strip() the input for each item.
Fixes#8174Closes#8190
Current aio-max-nr is set up statically to 1048576 in
/etc/sysctl.d/99-scylla-aio.conf.
This is sufficient for most use cases, but falls short on larger machines
such as i3en.24xlarge on AWS that has 96 vCPUs.
We need to tune the parameter based on the number of cpus, instead of
static setting.

dh_installinit --name <service> is for forcing install debian/*.service
and debian/*.default that does not matches with package name.
And if we have subpackages, packager has responsibility to rename
debian/*.service to debian/<subpackage>.*service.
However, we currently mistakenly running
dh_installinit --name scylla-node-exporter for
debian/scylla-node-exporeter.service,
the packaging system tries to find destination package for the .service,
and does not find subpackage name on it, so it will pick first
subpackage ordered by name, scylla-conf.
To solve the issue, we just need to run dh_installinit without --name
when $product == 'scylla'.

We currently deny running scylla_setup when umask != 0022.
To remove this limitation, run os.chmod(0o644) on every file creation

running in root user, but setting it to align permission with other files.

Currently we call firstNvmeSize before checking that we have enough
(at least 1) ephemeral disks. When none are found, we hit the following
error (see #7971):
```

firstDisk = ephemeral_disks[0]

This change reverses the order and first checks that we found
enough disks before getting the fist disk size.

Supported cross build by running CentOS7 on docker, now it's able to build
on Fedora.
It also supported switch container image, tested on Oracle Linux 7 and
CentOS 7/8.
Since we introduced relocatable package and offline installer, scylla binary itself can run almost any distributions.
However, setup scripts are not designed to run in unsupported distributions, it causes error on such environment.
This PR adds minimal support to run offline installation on unsupported distributions, tested on SLES, Arch Linux and Gentoo.

is_redhat_variant() is the function to detect RHEL/CentOS/Fedora/OEL,
and is_debian_variant() is the function to detect Debian/Ubuntu.
Unlike these functions, is_gentoo_variant() does not detect "Gentoo variants",
we should rename it to is_gentoo().
Currently, install.sh provide a way to customize sysconfig directory,
but sysconfig directory is hardcoded on script.
Also, /etc/sysconfig seems correct to use default value, but current
code specify /etc/default as non-redhat distributions.
Instead of hardcoding, generate generate python script in install.sh
to save specified sysconfig directory path in python code.

Add the seastar-cpu-map.sh to the SBINFILES variable, which is used to
create symbolic links to scripts so that they appear in $PATH.
Please note that there are additional Python scripts (like perftune.py),
which are not in $PATH. That's because Python scripts are handled
separately in "install.sh" and no Python script has a "sbin" symlink. We
might want to change this in the future, though.

Up until now, Scylla's debian packages dependencies versions were
unspecified. This was due to a technical difficulty to determine
the version of the dependent upon packages (such as scylla-python3
or scylla-jmx). Now, when those packages are also built as part of
this repo and are built with a version identical to the server package
itself we can depend all of our packages with explicit versions.
The motivation for this change is that if a user tries to install
a specific Scylla version by installing a specific meta package,
it will silently drag in the latest components instead of the ones
of the requested versions.
The expected change in behavior is that after this change an attempt
to install a metapackage with version which is not the latest will fail
with an explicit error hinting the user what other packages of the same
version should be explicitly included in the command line.
