Revert bad commit from merge conflict
Revert unneeded changes to application.json for admin console
LIVEOAK-197 Load all applications present in apps dir on boot
 - Remove ZeroApplicationDeployer as console is now deployed through presence of launcher/apps/admin
 - Add a new service to process appsDir and create applications if application.json found in a directory
 - Modify tests to add the admin application during setup as ZeroExtension no longer provides that functionality
