Since plugins are not part of Sahara core anymore, loading plugins
like we currently do fails when plugins are not installed.
Currently we check the list of loaded plugins by checking the CONF
file plugins session. To fix that, we are changing to check the list
of loaded plugins on the PluginManager variable loaded_plugins, this
way we can instead of failing to start sahara if a desired plugin
is not installed, we can warn that the plugin was not loaded and
continue the application.

It defines buildimages/CLI jobs, and reuses the global pylint job
and few jobs from sahara-tests (scenario, tempest), mimicking
the existing definitions of the legacy jobs.
Still missing: grenade (there is no common grenade job yet at this
point).
