Add jinja processing to alt command
With the new functionality, when the 'alt' command is called (or automatically triggered), any file with a name ending in '##yadm_tmpl' is treated as a jinja template. The template is processed by envtpl and the result is written to a file without the '##yadm_tmpl' name. The variables passed into the template processing are YADM_CLASS YADM_OS YADM_HOSTNAME YADM_USER These variables are set according to the normal rules for CLASS, OS, HOSTNAME, and USER during the alt processing.
