Draft: Updates location actions using vuex

I tried my best updating/simplifying the static and dynamic location actions but could not complete the work.

Here are some stuff still missing, that need to be done:

• pages/configurations/_configurationId/locations.vue
  • try-catch in created()
• serializers/jsonapi/DynamicLocationBeginActionSerializer.ts
  • add serialization for the device properties x,y,z
  • therefore you probably need to update services/sms/ConfigurationApi.ts:findRelatedDynamicLocationBeginActions() to include the information about that properties
• the method buildConfigurationTree of modelUtils/mountHelpers.ts is currently not working, as we load the configuration and actions separately
  • this method is currently used in location in following files:
    • pages/configurations/_configurationId/locations/dynamic-location-begin-actions/new.vue
    • pages/configurations/_configurationId/locations/dynamic-location-begin-actions/_actionId/edit.vue
    • pages/configurations/_configurationId/locations/dynamic-location-end-actions/new.vue
    • pages/configurations/_configurationId/locations/dynamic-location-end-actions/_actionId/edit.vue
  • the method is used there to provide information about the currently active device (devices of the hierarchy tree of the selected date)
    • this information should be provided via store using the new controller methods (see: Link)
