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."

Unfortunately this is not idempotent, however we surely want to sync
everything when salt.minion state is executed.
