Fixed quick-start demo 

### Fixes
* Fixed issue with collisions between users in the same project by appending their ldap to instances upon launch.

### Added
* Added a startup script to auto-delete instances after 10 mins
  * Note: Only the first instance launched has a public IP address so I added the startup script to that instance which auto-deletes the rest of them. Otherwise the startup script fails on all instances besides the first one.
