improve vagrant test and its documentation

RPM packages are now kept in output directory after build so that we
know exactly which packages to copy to the test. The test directory now
contains special directory for RPMs. Fedora developer portal is
referenced from README file.

+# Setup
+
+To run the tests in vagrant virtual machine, please follow this tutorial:
+https://developer.fedoraproject.org/tools/vagrant/vagrant-libvirt.html
+
+(run also `sudo systemctl start libvirtd`)
+
+# Using Vagrant
+
+To start a Vagrant box by hand, run `vagrant up` in this directory. To stop and remove all volumes run `vagrant destroy` again in this directory.
+
+# Troubleshooting
+
+In case you accidentally deleted `.vagrant` directory, you can use some of these commands in order to get rid of running instance:
+```
+$ virsh list # this should display test_default
+$ virsh managedsave-remove test_default
+$ virsh undefine test_default
+# or using vagrant cli tool
+$ vagrant global-status
+$ vagrant destroy <id>
+$ vagrant global-status --prune
+```
