[Reviewer: Matt] Homestead as HSS development

Fixes issues: metaswitch/crest#164, metaswitch/crest#162, metaswitch/crest#47. In conjunction with Phil's change of moving monit to upstart metaswitch/crest#148 should also be fixed. Also, included are ENTs for improved craft/syslog logs. Plus, command line tools for provisioning subscribers in the absence of Ellis.
You commented that you use this to print out the definitions for review.  That's a valid reason, but how will other people find this?  Do we have any documentation for this process (and where to get the output when you've done so)?
