In JobClient, the list_jobs function has a limit argument, which sets the number of jobs returned in a single request. The default value is is None in the library, which means "use the default limit from the backend service". That default value is (I believe) 10.

Had a request to use that upstream default value in the library to make the effect of different values clearer. Otherwise interpreting the behaviour of None is difficult (for example will there be paging in that case or all records are returned?)
