v0.8.0

This release fixes a lot on the CI front, includes new releases of guest operating systems and enables network multiqueue by default for relevant guests. This is a backwards compatible change as both the cluster and the guest VMs have no issues with that functionality according to our testing.

This release also fixes the issue with version dependent template names (introduced accidentally in v0.6.1). Since this would have negative impact on upgrades, we decided to fix the name automation and keep the names compatible with the v0.7.0 release.
