This class handles the actions of the jail. Creation, deletion or to
actions must be done through this class. This class is based on the
Mapping type, and the `add` method must be used to add new actions.
This class also starts and stops the actions, and fetches bans from
the jail executing these bans via the actions.
Parameters
----------
jail: Jail
The jail of which the actions belongs to.
Attributes
----------
daemon
ident
name
status
active : bool
Control the state of the thread.
idle : bool
Control the idle state of the thread.
sleeptime : int
The time the thread sleeps for in the loop.

Options for Python Action, used as keyword arguments for
initialisation. Default None.
Raises
------
ValueError
If action name already exists.
RuntimeError
If external Python module does not have `Action` class

a Gets bans merged once, a helper for lambda(s), prevents stop of executing action by any exception inside.
This function never returns None for ainfo lambdas - always a ticket (merged or single one)
and prevents any errors through merging (to guarantee ban actions will be executed).
[TODO] move merging to observer - here we could wait for merge and read already merged info from a database
Parameters
----------
overalljails : bool
switch to get a merged bans :
False - (default) bans merged for current jail only
True - bans merged for all jails of current ip address
Returns
-------
