CI Please Build—How to build your oVirt project on-demand

All projects in oVirt CI are built today post merge, using the 'build-artifacts' stage from oVirt's CI standards. This ensures that all oVirt projects are built and deployed to oVirt repositories and can be consumed by CI jobs, developers or oVirt users.

However, on some occasions a developer might need to build his project from an open patch. Developers need this capability in order to to examine the effects of their changes on a full oVirt installation before merging those changes. On some cases developers may even want to hand over packages based on un-merged patches to the QE team to verify that a given change will fix some complex issue or to preview a new feature on its early stages of development.

While it might seem that it covers alot and gives a good indication that the patch is good to be merged, unfortunately it is not always the case.

The reason it's not enough lies in oVirt's complexity and the fact it's a Virtualization project, which means the only real way to know if your patch didn't break things is to install oVirt and try running a few basic commands, like 'adding host', 'adding vm', 'creating snapshots', and other tasks you can only do if you have a full oVirt system up and running. Here is where OST comes in!
