In wait_action node change duration type from int to double (#3871)

* change duration tyype from int to double

* change "1" to "1.0" as default wait_duration value

* modify wait_action tests

* fix

* change int values to double in trees

* add usage of Duration::from_seconds()

* fix build failing issue

* delete whitespace
