[cloud] New module = elb_application_lb (#19491)

Browse Source 
* New module = elb_application_lb

* Update elb_application_lb.py

Adds support for rules, adds wait option for ALB creation, adds support for using target group names instead of ARNs when referencing target groups in rules. All additional features should be idempotent.

* Better exception error messages. Bump version_added. Pep8 fixes

* Add missing full stop to description

* Review changes and fixes

* Fix pep issues

* Fix up examples

* Fix pep8

* half way through sorting elb attributes

* Add access logs enabled param

* Finish implementing elb attributes

* Use paginator to get elbs

* Dont snake_case the tags

* Add listeners to return output and fixed up examples

* review changes

* fix line lengths

* pep8 fixes
