Generic system model for SaltClass based deployment

This repo is based on existing reclass-model (https://github.com/Mirantis/reclass-system-salt-model)

Contains default pillar data for various systems/apps. Use along with pillar data on - service level (enbeded in formula under /metadata) - cluster level (an class override for individual deployment)

Expected SaltClass root structure:

/srv/salt/env  # installed formulas
/srv/salt/saltclass/
  - nodes
  - services/
               # link installed formulas `<formula>/metadata/service`
               #
               # SaltClass fixup:
               # for i in $(grep -r -e '^applications:' -e '^parameters:' -l ${SALT_CLASS_SERVICE:-/usr/share/salt-formulas/reclass/service}); do
               #   sed -i 's/applications:/states:/g;s/parameters:/pillars:/g' $i;
               # done
  - classes/
     - system  # (this repo as subrepository)
     - cluster # (your overrides)
