where is ServiceContainer implementation?

[gattytto]

hello, I'm looking at both versions of PropelLaravel(develop and main branches) which make use of propel2 StandardServiceContainer and propel3 does not implement this.

I see some of the servicecontainer functions(from propel2) present in propel3 Runtime\Configuration class.

since PropelLaravel is specific to laravel and requires it, maybe the service container present in "illuminate" can be used https://laravel.com/docs/5.6/container

help, please?
