Replace Virtualbox based test fixtures with docker-compose

[alpar-t]

Fixtures: We have some fixtures (Kerberos, HDFS, SMB, idp) that use Vagrant with the Virtualbox provider. There isn't a string reason to use neither vagrant nor Virtualbox for these fixtures and we want to reduce reliance on VirtualBox in the build.

We would use docker images instead with docker-compose and the gradle-docker-compose-plugin.
This should work reliably across all OSes. We would skip these tests if docker-compose is not available.

Will require CI images to have docker-compose installed.

All worker images that are capable of running Docker do receive a docker label on them in Jenkins, so that can be used as a target for these particular jobs.
