apt_install() / apt_uninstall() may fail if background process running
apt operation, such as unattended-upgrades.
To avoid this, we need to add two things:
1. For apt-get install / remove, we need to option "DPkg::Lock::Timeout=-1"
to wait for dpkg lock.
2. For apt-get update, there is no option to wait for cache lock.
Therefore, we need to implement retry-loop to wait for apt-get update
succeed.

Unlike yum, "apt-get install" may fails because package cache is outdated.
Let's check package cache mtime and run "apt-get update" if it's too old.

The commitlog api originally implied that
the commitlog_directory would contain files
from a single commitlog instance. This is
checked in segment_manager::list_descriptors,
if it encounters a file with an unknown
prefix, an exception occurs in
commitlog::descriptor::descriptor, which is
logged with the WARN level.
A new schema commitlog was added recently,
which shares the filesystem directory with
the main commitlog. This causes warnings
to be emitted on each boot. This patch
solves the warnings problem by moving
the schema commitlog to a separate directory.
In addition, the user can employ the new
schema_commitlog_directory parameter to move
the schema commitlog to another disk drive.
By default, the schema commitlog directory is
nested in the commitlog_directory. This can help
avoid problems during an upgrade if the
commitlog_directory in the custom scylla.yaml
is located on a separate disk partition.
This is expected to be released in 5.3.
As #13134 (raft tables->schema commitlog)
is also scheduled for 5.3, and it already
requires a clean rolling restart (no cl
segments to replay), we don't need to
specifically handle upgrade here.
Fixes: #11867
Currently, --disks options does not allow symlinks such as
/dev/disk/by-uuid/* or /dev/disk/azure/*.
To allow using them, is_unused_disk() should resolve symlink to
realpath, before evaluating the disk path.

Even we have __escape() for escaping " middle of the value to writing
sysconfig file, we didn't unescape for reading from sysconfig file.
So adding __unescape() and call it on get().
It seems like distribution original sysconfig files does not use double
quote to set the parameter when the value does not contain space.
Adding function to detect spaces in the value, don't usedouble quote
when it not detected.
Fixes#9149
Current debug log is bit difficult to collect in CI, to find the debug log
we must know which script caused Exception.
Because the filename does not include prefix, and also specified
directory is shared with other programs.
To make things more easily, let's change debug log directory to /var/tmp/scylla.
Closes#10730
On 48b6aec16a we mistakenly allowed
check=True on systemd_unit.is_active(), it should be check=False.
We check unit's status by "systemctl is-active" output string,
it returns "active" or "inactive".
But systemctl command returns non-zero status when it returning
"inactive", so we are getting Exception here.
To fix this, we need new option "ignore_error=True" for out(),
and use it in systemd_unit.is_active().

To run scylla-housekeeping we currently use "sudo -u scylla <cmd>" to switch

[avi: regenerate frozen toolchain]
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.
related #10390Closes#10414
We currently does not able to get any error message from subprocess when we specified capture_output=True on subprocess.run().
This is because CalledProcessError does not print stdout/stderr when it raised, and we don't catch the exception, we just let python to cause Traceback.
Result of that, we only able to know exit status and failed command but
not able to get stdout/stderr.
This is problematic especially working on perftune.py bug, since the
script should caused Traceback but we never able to see it.
To resolve this, add wrapper function "out()" for capture output, and
print stdout/stderr with error message inside the function.
Fixes#10390Closes#10391
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.

As of now, 'systemd_unit.available' works ok only when provided

So, make it return boolean in both cases.

Currently, scylla-server fails to start on ARM instances because scylla_io_setup does not have preset parameters even instance type added to 'supported instance'.
To fix this, we need to add io parameter preset on scylla_io_setup.
Also, we mistakenly added EBS only instances at a004b1da30, need to remove them.
Instrances does not have ephemeral disk should be 'unsupported instance', we still run our AMI on it, but we print warning message on login prompt, and user requires to run scylla_io_setup.

* github.com:scylladb/scylla:
scylla_util.py: remove EBS only ARM instances from support instance list
scylla_io_setup: support ARM instances on AWS
Since we required ephemeral disks for our AMI, these EBS only ARM
instances cannot add in it is 'supported instance' list.
We still able to run our AMI on these instance types but login message
warns it is 'unsupported instance type', and requires to run
scylla_io_setup manually.
Currently, aws_instance.ephemeral_disks() returns both ephemeral disks
and EBS disks on Nitro System.
This is because both are attached as NVMe disks, we need to add disk
type detection code on NVMe handle logic.

Just like EBS disks for EC2, we want to use persistent disk on GCE.
We won't recommend to use it, but still need to support it.

On severl instance types in AWS and Azure, we get the following failure

We have scylla_prepare:configure_io_slots() running before the
scylla-server.service start, but the scylla_io_setup is taking place
before
1) Let's move configure_io_slots() to scylla_util.py since both
scylla_io_setup and scylla_prepare are import functions from it
2) cleanup scylla_prepare since we don't need the same function twice
3) Let's use configure_io_slots() during scylla_io_setup to avoid such
failure

Currently, 'if unit.is_active():' is always True since is_active()
returns result in string (active, inactive, unknown).
To avoid such scripting bug, change return value in bool.
When psutil.disk_paritions() reports / is /dev/root, aws_instance mistakenly
reports root partition is part of ephemeral disks, and RAID construction will
fail.
This prevents the error and reports correct free disks.

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().
