GitLab

- add skylake tests
- deactivate minsky runner for the time being

- Did not properly handle case when $HOST is not set
- String comparison with "[" is done with a single "="

Because it could be difficult to run the runner directly on miy01,
it is being run on dvl02, but the runner method is "ssh" and the
tests are then build and run on miy01

The legacy API is has been (internally) ported to use the new interface.
The intent is that users of the legacy API do not have to change their
codes.

Next step is to completely adapt the .gitlab-ci.yml file

Two issues: executable was named differently and the CI test names were
colliding
