fix(tests,kubevirt_vm): Make waiting for VM more robust

Browse Source 
This changes the runme.sh of the kubevirt_vm integration tests to retry
the connection to the VM until a login is possible. This is necessary
since it is not possible with Ansible alone to retry a task in case the
connection failed with the unreachable status. This can happen when the
sshd of the VM already accepts connections but a login is not yet
possible because the VM is still booting up.
