ansible issue w/ change handlers and tags

* apparently tag information is not flowing down to the change
handler via the meta dependencies.  The change handler can be
called independentently prior to the workaround and things will work

change workarounds to be role based

* group_by as a playbook to be called in front of
every playbook.  group_by is not workaround specific
and can be use through out all the playbooks

* role based workarounds will be more flexible than
the provious yml import.  With role based workarounds
will be more consistent with the rest of khaleesi

* include the defaults, files, and templates for each
workaround etc.
