initial commit for starting lms-preview role
Nginx log reconfiguration

* sends logs to /mnt/logs/nginx instead of /var/log. Note that on fresh
  server startup, nginx will still log to /var/log until it reads its
  configuration.
* Installs logrotate configuration for freshly moved nginx logs
* Some directory and file permissions fixups
* Improved order of operations on nginx installation/bringup

Tag tasks update or install

* update tasks are meant to be the fast ones and the ones we want to be
  sure to always do (directory creations, permissions, etc.)
* install tasks are all the really slow things, like the git repo clone
  and package installations
* Every task can by run by --tags=install,update - which is the same as
  having no tags at all.
