282cd0df7c dist/docker: Update SCYLLA_REPO_URL and VERSION defaults
Update the SCYLLA_REPO_URL and VERSION defaults to point to the latest
unstable 4.0 version. This will be used if someone runs "docker build"
locally. For the releases, the release pipelines will pass the stable
version repository URL and a specific release version.

de19496ff7 dist/docker: Add VERSION argument to Dockerfile (#5845)
Currently, the Dockerfile installs the latest version of Scylla. Let's
add a VERSION argument to Dockerfile, which explicitly specifies the
version to ensure scripts, for example, always build the expected
version. If no VERSION is specified for "docker build", use the default
value of "666.development", which is the version number for latest
nightly.

99cedf737c docker: rsyslog configuration fixes
The introduction of rsyslog had two errors in it.
Both errors are non fatal and the docker still works,
however, the system is left in a wrong state in which
supervisord marks rsyslogd service as failed (after several
failed retry attempts). Another bug in the configuration
causes rsyslog to output an error.

1) An inclusion command from a newer version was used
in rsyslogs main configuration file. This caused to rsyslog
to complain during startup but it didn't do much damage since
rsyslog converts every unrecognised command to a message command.
2) in the supervisord definition of the service, rsyslogd is ran
without the -n option which means it defaults to automatically
switch to the background. Supervisord interpret this as an unexpected
process termination and retries to start the process (unsuccessfully
because rsyslog protects itself from having multiple processes of
itself) and eventually marks it as down although it is fully up and
running.
This commit fixes both configuration problems.

Tests: Build and run docker and validate the errors are gone.

This reverts commit 65aadad9a6. It causes

the user should be warned).

fa423e25d4 scylla_setup: shows up usage when --nic is not specified & eth0 is not available
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.

f21123b3ae scylla_io_setup: Improve error message for unsupported EC2 instance types (#5561)
Currently --ami does not check instance types, creates invalid

It actually won't occur on AMI startup, since scylla_ami_setup only
invoke scylla_io_setup --ami when the instance is supported, so we don't
get the issue on startup, but we still get when we run scylla_io_setup
manually.

When the product name is other than "scylla", the debian

However, if there are no such files in the directory
the script will fail since the renaming command will
get the wildcard string instrad of an actual file name.

if there are any.

263385cb4b dist: stop replacing /usr/lib/scylla with symlink (#5530)
Since we merged /usr/lib/scylla with /opt/scylladb, we removed
/usr/lib/scylla and replace it with the symlink point to /opt/scylladb.
However, RPM does not support replacing a directory with a symlink,
we are doing some dirty hack using RPM scriptlet, but it causes
multiple issues on upgrade/downgrade.
(See: https://docs.fedoraproject.org/en-US/packaging-guidelines/Directory_Replacement/)

To minimize Scylla upgrading/downgrade issues on user side, it's better
to keep /usr/lib/scylla directory.
Instead of creating single symlink /usr/lib/scylla -> /opt/scylladb,
we can create symlinks for each setup scripts like
/usr/lib/scylla/<script> -> /opt/scylladb/scripts/<script>.

d7795b1efa scylla_setup: Support for enforcing optimal Linux clocksource setting (#5499)
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.

of them is missing from `dist/ami/files`. If they are missing,
look them up in build/redhat/RPMS/x86_64 so that if reloc/build_rpm.sh
was run manually before dist/ami/build_ami.sh we can just collect
the built rpms from its output dir.

If we're still missing any rpms, then run reloc/build_rpm.sh
and copy the required rpms from build/redhat/RPMS/x86_64.

765db5d14f build_ami: Trim ami description attribute to the allowed size
The ami description attribute is only allowed to be 255
characters long. When build_ami.sh generates an ami, it
generates an ami description which is a concatenation
of all of the componnents version strings. It can
happen that the description string is too long which
eventually causes the ami build to fail. This patch
trims the description string to 255 characters.
It is ok since the individual versions of the components
are also saved in tags attached to the image.

Tests:
 1. Reproduced with a long description and
    validated that it doesn't fail after the fix.

Fixes #5435

4333b37f9e scylla_setup: Support for enforcing optimal Linux clocksource setting (#5379)
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.

9c63cd8da5 sysctl: reduce kernel tendency to swap anonymous pages relative to page cache (#5417)
The vm.swappiness sysctl controls the kernel's prefernce for swapping
anonymous memory vs page cache. Since Scylla uses very large amounts
of anonymous memory, and tiny amounts of page cache, the correct setting
is to prefer swapping page cache. If the kernel swaps anonymous memory
the reactor will stall until the page fault is satisfied. On the other
hand, page cache pages usually belong to other applications, usually
backup processes that read Scylla files.

This setting has been used in production in Scylla Cloud for a while
with good results.

Users can opt out by not installing the scylla-kernel-conf package
(same as with the other kernel tunables).

c9d8606786 dist/common/scripts/scylla_ntp_setup: relax RHEL version check
We may able to use chrony setup script on future version of RHEL/CentOS,
it better to run chrony setup when RHEL version >= 8, not only 8.

Note that on Fedora it still provides ntp/ntpdate package, so we run
ntp setup on it for now. (same on debian variants)

c5a95210fe dist/common/scripts/scylla_setup: list virtio-blk devices correctly on interactive RAID setup
Currently interactive RAID setup prompt does not list virtio-blk devices due to
following reasons:
 - We fail matching '-p' option on 'lsblk --help' output since misusage of
   regex functon, list_block_devices() always skipping to use lsblk output.
 - We don't check existance of /dev/vd* when we skipping to use lsblk.
 - We mistakenly excluded virtio-blk devices on 'lsblk -pnr' output using '-e'
   option, but we actually needed them.

To fix the problem we need to use re.search() instead of re.match() to match
'-p' option on 'lsblk --help', need to add '/dev/vd*' on block device list,
then need to stop '-e 252' option on lsblk which excludes virtio-blk.

Additionally, it better to parse 'TYPE' field of lsblk output, we should skip
'loop' devices and 'rom' devices since these are not disk devices.
