AEMaaCS readyness

[LFDave]

Note: this is work in progress to collect topics that come up in regards to compatibility with AEMaaCS. Below were primary findings from having a quick look.

Tasks

• move mutable content (/content/dam/frontify-aem-connector) from ui.apps
• replace legacy /etc/cloudservices
• update deprecated SlingSettingsService in RunmodeUtil

Optimizations

• narrow down filters in ui.apps are (/apps/cq, /apps/wcm)
• add primary type to nodes in ui.apps/src/main/content/jcr_root/apps/wcm/core/content/editor/.content.xml
• considering sling resource merger the nodes should not even be part of the xml
