Arx Cruz a9af6c823d Remove static class loader
This commit remove the static class loader and add a dynamic one.
This is done using a new property available_classes that checks for
classes inherited by Services and generate a list of it.
It also change how tempestconf identify available services using the
list_services api instead of get_catalog api from tempest lib.
This way, tempestconf are no longer generating Services objects for
services that doesn't have a specialized class, but still set the
defaults for true or false if a service is running or not.
The discover method has changed to get the services from the list of
services instead of from the catalog.
