Better define configuration and provide examples.

* controller: Unpack results to correct directory, load the
configuration from new place, call run_remote with proper
arguments, generate 'results.html' with result_stats script.
* ansible/run_include: Adjust to better simulate run_remote.
* ansible/fedora.yml: Adjust for fixed configuration.
* run_remote: Likewise. Also small issues with option parsing
fixed.
* config.sh.template: Moved as config/config.sh.template.
* config/config.sh.template: Copyyed from /config.sh.template,
better documented options.
* run: Fix typo - use 'while read i' instead of 'for i in'.
* config/os/EXAMPLE.sh: New file - exmaple configuration.
* private/os/EXAMPLE.yml: Likewise.
* config/hosts.template: Likewise.
* dist.include: New file with file patterns that should be
distributed to test machine.
* dist: Distribute only those files which are necessary.
* config/.gitignore: New gitignore file.

Controller script runs the script on remote machine (OpenStack),
downloads the results, stores the result into its own
result-database and re-generates statistics for runs done so far.
It will be able to upload the results to "presenter" machine.

* config.sh.template: New doc file.
* controller: New file (the central script for CI).
* runner/result_stats: New file. Based on downloaded results from
testing machine, it generates single html file with stats.
* runner/result_templates/html.tmpl: New file. Template for ^^^.
