mandos-ctl: Separate determining what to do and actually doing it

* mandos-ctl (defaultkeywords): Removed; value moved into
                                PrintTableCmd.
  (Command): New abstract base class for commands to be run.
  (PrintCmd, PropertyCmd): New abstract classes for commands.
  (ValueArgumentMixIn, MillisecondsValueArgumentMixIn): New mixins for
                                                        commands.
  (PrintTableCmd, DumpJSONCmd, IsEnabledCmd, RemoveCmd, ApproveCmd,
  DenyCmd, EnableCmd, DisableCmd, BumpTimeoutCmd, StartCheckerCmd,
  StopCheckerCmd, ApproveByDefaultCmd, DenyByDefaultCmd,
  SetCheckerCmd, SetTimeoutCmd, SetExtendedTimeoutCmd,
  SetApprovalDelayCmd, SetApprovalDurationCmd): New commands.
  (main): Don't look directly at options and do things; instead go
          through all options and add commands to a list, then run all
          commands on clients.
