Shared folder is not required for tests.
We should avoid hitting the error :
```
uninitialized constant VagrantPlugins::ProviderLibvirt::Action::ShareFolders
```
Also, disabling it might reduce the needed time in certains cases for the VMs
to be started.

If two environments are using the same subnet, we will get trouble
because of ips addresses conflicts.
This commit ensures each scenario has a uniq subnet for both public and cluster
network so we can setup several test environment at a time on a same hypervisor.

Since we are hitting this bug :
https://bugzilla.redhat.com/show_bug.cgi?id=1324587
eg:
`failed: internal error: Monitor path /var/lib/libvirt/qemu/domain-bs-docker-cl
uster-dmcrypt-journal-collocation_mon0_1499294943_ba9faf7bf296533177f6/monitor.
sock too big for destination`
and we can't upgrade libvirt in our CI for some reason
we need to get the directories name shorter in order to workaround this
issue
