To run scylla-housekeeping we currently use "sudo -u scylla <cmd>" to switch
scylla user, but it fails on some environment.
Since recent version of Python 3 supports to switch user on subprocess module,
let's use python native way and drop sudo.

On acaf0bb we applied out() just for perftune.py because we had issue #10390
with this script.
But the issue can happen with other commands too, let's apply it to all
commands which uses capture_output.

Currently, cloud related code have cross-dependencies between
scylla and scylla-machine-image.
It is not good way to implement, and single change can break both
package.
To resolve the issue, we need to move all cloud related code to
scylla-machine-image, and remove them from scylla repository.
Change list:
- move cloud part of scylla_util.py to scylla-machine-image
- move cloud part of scylla_io_setup to scylla-machine-image
- move scylla_ec2_check to scylla-machine-image
- move cloud part of scylla_bootparam_setup to scylla-machine-image

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
Online discard asks the disk to erase flash memory cells as soon
as files are deleted. This gives the disk more freedom to choose
where to place new files, so it improves performance.
On older kernel versions, and on really bad disks, this can reduce
performance so we add an option to disable it.
Since fstrim is pointless when online discard is enabled, we
don't configure it if online discard is selected.
I tested it on an AWS i3.large instance, the flag showd up in
`mount` after configuration.
Closes#9608
Message changed according to what 'scylla_bootparam_setup' currently does
(set a clock source at boot time) instead of of what it used to do in
the past (setting huge pages).
Closes#9116.
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.

We currently deny running scylla_setup when umask != 0022.
To remove this limitation, run os.chmod(0o644) on every file creation
to allow reading from scylla user.
Note that perftune.yaml is not really needed to set 0644 since perftune.py is
running in root user, but setting it to align permission with other files.

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().
node_exporter had been added to scylla-server package by commit
95197a09c9.
So we can enable it by default for offline installation.

scylla_setup command suggestion does not shows an argument of --io-setup,
because we mistakely stores bool value on it (recognized as 'store_true').
We always need to print '--io-setup X' on the suggestion instead.
Also, --nic is currently ignored by command suggestion, need to print it just like other options.

This patch adds an option to scylla_setup to configure an rsyslog destination.
The monitoring stack has an option to get information from rsyslog it
requires that rsyslog on the scylla machines will send the trace line to
it.
The configuration will be in a Scylla configuration file, so it is safe to run it multiple times.

We initially implemented run() and out() functions because we couldn't use
subprocess.run() since we were on Python 3.4.
But since we moved to relocatable python3, we don't need to implement it ourselves.
Why we keep using these functions are, because we needed to set environemnt variable to set PATH.
Since we recently moved away these codes to python thunk, we finally able to
drop run() and out(), switch to subprocess.run().
On Ubuntu 16/18 and Debian 9, LimitNOFILE is set to 4096 and not able to override from
user unit.
To run scylla-server in such environment, we need to turn on developer mode and show
warnings.

We need to skip internet access on offline installation.
To do this we need following changes:
- prevent running yum/apt for each script
- set default "NO" for scripts it requires package installation
- set default "NO" for scripts it requires internet access, such as NTP
See #7153Fixes#7182
hugepages and libhugetlbfs-bin packages is only required for DPDK mode,

do_verify_package written only for .rpm/.deb, does not working correctly

We should check file existance for the environment, not by package existance
using rpm/dpkg.

To make the "scylla_setup" interface similar to Docker image, let's add
a "--io-setup ENABLE" command line option. The old "--no-io-setup"
option is retained for compatibility.
Since we set 'eth0' as default NIC name, we get following error when running scylla_setup in non-interactive mode without --nic parameter:
$ sudo scylla_setup --setup-nic-and-disks --no-raid-setup --no-verify-package --no-io-setup
NIC eth0 doesn't exist.
It looks strange since user actually does not specified 'eth0', they might forget to specify --nic.
I think we should shows up usage, when eth0 is not available on the system.

A Linux machine typically has multiple clocksources with distinct
performances. Setting a high-performant clocksource might result in
better performance for ScyllaDB, so this should be considered whenever
starting it up.
This patch introduces the possibility of enforcing optimized Linux
clocksource to Scylla's setup/start-up processes. It does so by adding
an interactive question about enforcing clocksource setting to scylla_setup,
which modifies the parameter "CLOCKSOURCE" in scylla_server configuration
file. This parameter is read by perftune.py which, if set to "yes", proceeds
to (non persistently) setting the clocksource. On x86, TSC clocksource is used.
