Adding integration tests for async fire-and-forget checking

Also updated the CHANGELOG for the feature

CHANGELOG.md

@@ -16,6 +16,7 @@ Major changes:
 * command_warnings feature will warn about when usage of the shell/command module can be simplified to use core modules - this can be enabled in ansible.cfg
 * new omit value can be used to leave off a parameter when not set, like so module_name: a=1 b={{ c | default(omit) }}, would not pass value for b (not even an empty value) if c was not set.
 * developers: 'baby JSON' in module responses, originally intended for writing modules in bash, is removed as a feature to simplify logic, script module remains available for running bash scripts.
+* async jobs started in "fire & forget" mode can now be checked on at a later time.
