* Action factory register actions in DB at starting
* Added script tools/sync_db.sh for sync with db
(Updates system actions, it is required before
first Mistral launch)
* Changed init Mistral in devstack: we must do
sync_db before the launching.
* Since we have to write all actions in DB, unit
test are also modified:
* Now in tearDown() we don't drop db at all,
but just delete all things except Actions.
* Created heavy_init() method as a replacement
setUpClass(), see comments in tests/base.py
* Register actions operation is too much expensive
operation so we create db and init actions in
heavy_init() method.
TODO:
* Provide executor info to construct action class in
runtime using action_factory
* Modify/write an instruction 'How to start Mistral'
