lv-create: use the template module to write log file

The copy module will not expand the template and render the variables
included, so we must use template.

Creating a temp file and using it locally means that you must run the
playbook with sudo privledges, which I don't think we want to require.
This introduces a logfile_path variable that the user can use to control
where the logfile is written to, defaulting to the cwd.
