fixed issues in config/ansible tests, added some retry/delay capability
when tasks fail
First addition of the default task component functionality
Added a 'no_delay' option to the execution agent so that tests can run
faster if they aren't actually doing any Ansible stuff.
Initial steps in wrapping a Config class in the ConfigClassTask wrapper
working
fixed up some problems with using the ConfigClassTask when wrapped in a
MultiTask. We now appear to be doing all dependency and graph generation
properly.
