mandos-ctl: Refactor D-Bus operations

* mandos-ctl (dbus): Rename imported module to "dbus_python".
  (main): Only create a bus object and do everything via that object.
  (get_mandos_dbus_object): Remove and move code into dbus or
                            dbus_python_adapter namespaces.
  (if_dbus_exception_log_with_exception_and_exit): - '' -
  (SilenceLogger): - '' -
  (dbus): New; move everything dbus-specific into this module-like
          namespace.
  (dbus_python_adapter): New; move everything specific to the
                         dbus-python D-Bus module into this
                         module-like namespace.
  (command.Base.run): Take only a bus argument; use only that.  Pass
                      "client" argument as a D-Bus object path string,
                      not a dbus-python proxy object.  All derivatives
                      adjusted.
  (command.IsEnabled.is_enabled): Remove.
  (command.Approve, command.Deny, command.Remove,
  command.PropertySetter): Do no logging of D-Bus commands, and use
  only bus, not client, to do D-Bus calls.
  (command.DumpJSON.dbus_boolean_to_bool): Remove; move filtering to
                                           dbus_python_adapter.
  (command.Enable, command.Disable, command.StopChecker,
  command.ApproveByDefault): Use normal Python booleans instead of
  dbus-python's special Boolean types.
  (Unique): New; move here out from inside TestPropertySetterCmd.
  (Test_get_mandos_dbus_object): Remove.
  (Test_get_managed_objects): - '' -
  (Test_dbus_exceptions): New.
  (Test_dbus_MandosBus): - '' -
  (Test_dbus_python_adapter_SystemBus): - '' -
  (Test_dbus_python_adapter_CachingBus): - '' -
  (Test_commands_from_options): Don't create mock client proxy
  objects, define dict of client properties and use a mock dbus to
  verify that the correct D-Bus calls are made.  Also remove any types
  specific to dbus-python.
  (TestEnableCmd, TestDisableCmd, TestStartCheckerCmd,
  TestStopCheckerCmd, TestApproveByDefaultCmd, TestDenyByDefaultCmd):
  Use normal Python booleans instead of dbus-python's special Boolean
  types.
  (TestPropertySetterValueCmd.runTest): Remove; unnecessary.
