[Open-scap] Public Jenkins infrastructure

[Zbynek Moravec]

Hi contributors,

We have make our Jenkins server public - https://jenkins.open-scap.org/ (self signed certificate currently).

Test-machines with Fedora22/RHEL6/RHEL7 are used.

When you push something to your pull requests, Jenkins will automatically start testing (or ask admin to verification).

White-list for automatic testing currently should contains people which have ever contributed to OpenSCAP/scap-security-guide.

Tips:
 - If you don't want to test your your pull request automatically, you can add "[skip ci]" phrase to pull request description.
 - If you are in admin-list(currently OpenSCAP team in Brno), you can control jenkins testing by pull-request comments:
    - "ok to test" to accept this pull request for testing
    - "test this please" for a one time test run
    - "add to whitelist" to add the author to the whitelist


If you have any tips/issue with jenkins, feel free to contact me.
