Allow value to be bool where 'yes'/'no' are in choices (#2593)

* Changed type of 'details' argument to bool on ecs_service_facts module.

* Changed type of 'autostart' argument to bool on virt_* modules.

* Changed types of 'autoconnect' and 'stp' argument to bool on nmcli module.
('create_connection_bridge(self)' and 'modify_connection_bridge(self)' are not implemented yet?)

* Added conversion of 'value' argument when 'vtype' is boolean on debconf module.
