Remove reference to non-existant container service
Add support for extensions to prepend configuration for the db_driver option. If "cannotBeOverwritten()" is called then any extension trying to prepend the configuration can not modify the configuration value which makes the application configuration have to be more explicit. Having this support is useful where a child bundle to the FOSOAuthServerBundle might already know the DB driver that needs to be used.

The Mongo extension is already available so we can enable it without using pecl. There is no need to support testing several versions of the driver.
This also uses the global composer setup available on Travis and adds PHP 5.6 testting
