Make EX_APP_CONTAINER_PREFIX configurable #523
Description
Describe why it is important and where it will be useful
If you have several Nextcloud instances on the same host. It would be good to be able to run several proxys that has its own prefix configured on the same host.
Right now it is nc_apps and it make it impossible to register two proxies on the same host (for development puproses, testing and simpler hosted solutions)
Describe your proposed solution
Either have this as a variable within the web interface or as an occ setting. Create a prefix for the current instance.
Describe alternatives you've considered, if relevant
