[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.
I don't think we've opened the port yet, so this log is misleading (as it says it's been successfully opened).
