low: cibconfig: Fix vim modeline

Fix the syntax of the vim modeline.

To enable vim modelines, add this to .vimrc:

  set modeline
  set modelines=5
high: report: Find nodes for any log type (boo#900654)

Checking only for ha-log.txt is not good since some
nodes collect to different file names.
high: hb_report: Collect logs from journald (boo#900654)

Uses journalctl to collect logs for the report period.
