Improvements to the jenkins_build module and new jenkins_build_info module (#7204)

* Add detach option so the task doesn't wait until the Jenkins job is finished

* Add new time_between_checks to be able to configure the sleep time between requests

* New jenkins_build_info to get information about a specific build

* Add version_added to the new module

* Add changelog fragment for jenkins_build changes

* Fix tests that required the python-jenkins module

* Remove tests that failed

Doesn't really make sense to test that with a mock

* Fix pep8 error

* Update maintainers for the jenkins_build and jenkins_build_info modules

* Improve format and add link to PR

* Move version_added documentation to the right file

* Fix incorrect examples

* Improve text format

* Fix incorrect code style

* Fix incorrect YAML for documentation

* Add version_added documentation to the new options
