Review "view logs on Fedora" quick-doc

- Remove Caution
- Review and Check View Log Information via Systemctl
- Add Using journalctl to View Log Information for a Specific Service
- Add to know more about systemd -> understanding-and-administering-systemd
- Sections can be moved up one level replaceing rsyslog
- Improve con_viewing-logs.adoc with adding some usefull information
- Change in using nano and vim to you can use favourite text editor
- Remove rsyslog completly
- Add -b and --list-boots if the user needs flter log messages for the current boot or view old log's
- instead of using bold for commands and file/folder names, maybe make them monospace too. That does'nt work in _NOTE_
- "Using the command line to open log files in a text editor" -> "Use a text editor" as a separate section.
- Observe a Warning when editing view_log.adoc and there is a PR in ASCCIDOCTOR
https://github.com/asciidoctor/asciidoctor/issues/2855.
