Implement SharedActionsData for action groups

- holds common relevant data between actions.
- currently supports only *cdrlog, making the process more reliable
and less repetitive. It also provides access to more information about
actions when creating CDRs.
- easier to scale.
- removes the need for cloning accounts before executing a group of
actions.
- added Actions method to check if specific action types exist inside.
