The class handles the initialisation of a filter, and actions. It's
role is then to act as an interface between the filter and actions,
passing bans detected by the filter, for the actions to then act upon.

Parameters
----------
name : str
        Name assigned to the jail.
backend : str
        Backend to be used for filter. "auto" will attempt to pick
        the most preferred backend method. Default: "auto"
db : Fail2BanDb
        Fail2Ban persistent database instance. Default: `None`
