This reverts commit 0cd19b9ea1.

Change-Id: Iea9bc493c246d2c4fdee48d58883d21a10ebf054

The patch adds _orchestrate.conf file to salt minion
configuration. Its template searches for "/meta/salt.yml"
file across all installed formulas and parses them if found.
As of now config will contain following data, e.g.:
orchestration:
  deploy:
    applications:
      cinder:
        priority: 150
      keystone:
        priority: 100

Application priorities will be used later for salt deploy
orchestration

The patch adds ability to configure REDIS as cache
backed for salt-master to be used as distibuted cache
further.

Currently the CI job fails with module not found errror.
AttributeError: 'module' object has no attribute 'check_refresh

The reason is new version of salt tries to call
salt.utils.pkg.check_refresh which is not available in 2016.11.3 but is
available in 2016.11.6.
Reference:
1. https://github.com/saltstack/salt/blob/v2016.11.3/salt/states/pkg.py
2. https://github.com/saltstack/salt/blob/v2016.11.6/salt/states/pkg.py#L1819

The fix proposed here is to use pkg.installed instead of pkg.latest.
It's not a good idea to always update salt whenever the salt state is
run, this may introduce failures unknown to the user. There is a pipeline
to update packages which should be used for updating to latest.
pkg.latest generally isn't a good way to write idempotent formulas. See
official salt docs: "Generally it is better for the installed function
to be used, as latest will update the package whenever a new package is
available."

Previous approach fails when all of formulas are installed from git.

Install all pkgs for formulas together.

source:engine metadata created - defaults to pkg
installation, pip installation alternative added
