[BUG] Formula try do enable for all unittypes

[unix196]

Formula support this unittypes - https://github.com/saltstack-formulas/systemd-formula/blob/master/systemd/units/unittypes.yaml.
In this state https://github.com/saltstack-formulas/systemd-formula/blob/master/systemd/units/init.sls#L21 formula try doing enable for all types, but it is not always possible to do this, for example:

systemctl cat browser.target
[Install]
WantedBy=multi-user.target

[Unit]
After=network.target
Description=Chromium target
Wants=browser-runner@1.service
Wants=browser-runner@2.service
Wants=browser-runner@3.service

systemctl cat browser-runner@.service
[Service]
ExecStart=some_command
Group=chromium
...
Slice=chromium.slice
Type=simple

[Unit]
After=network.target
Description=Browser runner %i
PartOf=browser-runner.target


systemctl cat chromium.slice
[Slice]
MemoryLimit=20G

[Unit]
Before=slices.target
DefaultDependencies=False
Description=Limited resources for Chromiums

I can enable target unit, but this action not valid for the current config service(service with multiple instances) and slice units. Code where define unit_status. I think can be done like this:

systemd/units/init.sls
 -     {% set unit_status = 'disable' if unitconfig.enabled is defined and unitconfig.enabled == false else 'enable' %}
+ {#      {% set unit_status = 'disable' if unitconfig.enabled is defined and unitconfig.enabled == false else 'enable' %} #}
...
+      {% if unitconfig.enabled is defined %}
 +     {% set unit_status = 'disable' if unitconfig.enabled == false else 'enable' %}
systemd_systemd_units_cmd_enable_or_disable_{{ unit }}_{{ unittype }}:
  cmd.wait:
    - name: systemctl {{ unit_status }} {{ unit }}.{{ unittype }}
    - watch:
      - cmd: reload_systemd_configuration
+      {% endif %}

In pillar explicitly define enabled variable.
This way state will try enable only necessary unittypes.
