Export journal files from devstack services
This performs a number of logging collection services
- Export the systemd journal in native format
- For every devstack service, export logs to text in a file named
screen-*to maintain legacy compatability when devstack services used to run in a screen session and were logged separately. - Export a syslog-style file with kernel and sudo messages for legacy compatability.
Writes the output to the logs/ subdirectory of
stage_dir.
