controller: better connect with other utilities

* controller/bin/dtf-controller.in (subcommand): Generate
stdout and stderr files separately.
(child_task): Generate '*.err' and '*.out' logs for subcommands.
Call dtf-run-remote with --distro/--distro-version options.  Call
the dtf-result-stats finally and save its output to results.html.
(main): Simple debugging info and comment adjusting.
* controller/libexec/dtf-commit-results.in: Tak three arguments
now.
* controller/libexec/dtf-result-stats.in: Better read the
'tester/run' output.
* controller/share/dtf-controller/ansible/playbooks/fedora.yml:
Run the 'run --force' instead of 'run' on remote host.
* controller/share/dtf-controller/results-stats-templates/html.tmpl
React on exit_status 2.
