[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.
Does this mean that all logs go to stdout and syslog?  Is this right?  Why do they still go to stdout?  (This may just come back to needing better commenting - I can't tell if this code is right without knowing what it's trying to do.)
