scylla_io_setup condition for nr_disks was using the bitwise operator
(&) instead of logical and operator (and) causing the io_properties

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):
```
File "/opt/scylladb/scripts/libexec/scylla_io_setup", line 239, in
if idata.is_recommended_instance():
File "/opt/scylladb/scripts/scylla_util.py", line 311, in is_recommended_instance
diskSize = self.firstNvmeSize
File "/opt/scylladb/scripts/scylla_util.py", line 291, in firstNvmeSize
firstDisk = ephemeral_disks[0]
IndexError: list index out of range
```
This change reverses the order and first checks that we found
enough disks before getting the fist disk size.

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

To connection-less environment, we need to add node_exporter binary

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.

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

If the /etc/rsyslog.d/ directory exists (that means the current system
runs rsyslog) it will ask if to add rsyslog configuration and if yes, it
would run scylla_rsyslog_setup.

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().
scylla_rsyslog_setup adds a configuration file to rsyslog to forward the
trances to a remote server.
It will override any existing file, so it is safe to run it multiple
times.
It takes an ip, or ip and port from the users for that configuration, if
no port is provided, the default port of Scylla-Monitoring promtail is
used.

If scylla_raid_setup script called without --raiddev argument
then try to use any of /dev/md[0-9] devices instead of only
one /dev/md0. Do it in this way because on Ubuntu 20.04
/dev/md0 used by OS already.

DEBIAN_FRONTEND environment variable was added just for prevent opening
dialog when running 'apt-get install mdadm', no other program depends on it.
So we can move it inside of apt_install()/apt_uninstall() and drop scylla_env,
since we don't have any other environment variables.
To passing the variable, added env argument on run()/out().
We currently set PATH for relocatable CLI tools in scylla_util.run() and
scylla_util.out(), but it doesn't work for perftune.py, since it's not part of
Scylla, does not use scylla_util module.
We can set PATH in python thunk instead, it can set PATH for all python scripts.

Retry mechanism didn't work when URLError happend. For example:
urllib.error.URLError: <urlopen error [Errno 101] Network is unreachable>
Let's catch URLError instead of HTTP since URLError is a base exception
for all exceptions in the urllib module.

when calling curl and exception is raised we can see unnecessary log messages that we can't control.
For example when used in scylla_login we can see following messages:
WARNING:root:Failed to grab http://169.254.169.254/latest/...
WARNING:root:Failed to grab http://169.254.169.254/latest/...
Initial image configuration failed!
To see status, run
'systemctl status scylla-image-setup'
On some environment such as CentOS8, journalctl --user -xe does not work
since journald is running in volatile mode.
The issue cannnot fix in non-root mode, as a workaround we should logging to
a file instead of journal.
Also added scylla_logrotate to ExecStartPre which rename previous log file,
since StandardOutput=file:/path/to/file will erase existing file when service
restarted.
