ffdc: Integrate ffdc script into robot framework flow.

This commit provides interface to enable automation tests (robot/jenkins)
to activate the new cli ffdc collector.

- Patchset 1: Initial commit for review.
- Patchset 2: Redesing and fixing issues
- Patchset 3: Fix build issue (pycodestyle)
- Patchset 4: Default ffdc store location running direct CLI
- Patchset 5: Addressing review comments and questions
- Patchset 6: Restore direct CLI default location to /tmp
- Patchset 7: Addressing issues from comments
              Also extend socket timeout for long-running command peltool -a
- Patchset 8: Use Builtin().log_to_console("") method in the bridge code
- Patchset 9: Rebase

Tests:
- Standalone script: python3 ./ffdc/collect_ffdc.py
- Within robot env: python3 -m robot .... -v FFDC_DEFAULT:0 ./tools/myffdc.robot
