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.

The "images" environment has sitepackages=True, required by the
Python binding for libguestfs (not on pip).
Also, set the Ubuntu kernel so that it can be read by normal.
This affected (and was fixed) many other users of libguestfs. See:

Each review which adds support for another plugin should change
the support matrix defined in the script.
Add the binary dependencies required for the sahara-image-pack
command.
