This change adds support for installation of other formula dependencies
during run of salt.minion state. Due to this, other states are able to
run successfuly on first run because their modules' dependencies are
already satisfied and loaded.

Issues:
* cmd.wait doesn't work correctly with bg=True
* cmd.wait will be deprecated in next releases [1]
* watch/watch_in work differently than onchanges/onchanges_in as some
* module override mod_watch()

This patch does:
* Replaces cmd.wait to cmd.run with onchanges.
* On any config file changes salt_minion_service_restart will be
  triggered so salt master will get state immediately because of bg=True
* salt_minion_service is used only for service enablement

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.
