fuel, armband: basic healthcheck in verify jobs

fuel, armband: basic healthcheck in verify jobs

Enable Functest based gating for jobs:
- fuel-verify-*
- armband-verify-*
This includes Functest suite 'healthcheck' and testcase 'vping_ssh',
similar to Compass4NFV verify jobs.

While at it, remove 'basic' phase from verify jobs, as linting is
handled via separate jobs on Jenkins master and there's no other
reason to keep it around.
