TODO:
* password prompting needs to be implemented, but is being worked on
  as part of the become privilege escalation changes

Was using persist_files=True when specifying the create paramater,
which breaks pipelining. Switched to use delete_remote_tmp=False instead,
which is the proper way to preserve the remove tmp dir when running
other modules from the action plugin.

changed from hash_merge to combine vars which resets default to

Note: In v1 we fix this by transforming into unicode just before we use
it (when we send it to jinja2) because jinja2 cannot handle non-ascii
characters in str.

In v2 our model is that all text values need to be stored as unicode
type internally.  So we transform this to unicode when we read it from
the inventory file and save it into the internal dict instead.

use to_unicode() in _jinja2_vars if type is str.
