[TESTS] cleanup tests and remove reference to ubuntu16

the basic_vm test was historically called ubuntu16...
as we are now delaing more with ubuntu18 or ubuntu20, the reference
to the version16 is a bit old

- Replace ubuntu16 by basic_vm
- Use ubuntu20 instead of Ubuntu16
- Replace onap.small by m1.small to be natively compatible with any Openstack
  (default flavor)
