Service with dependency to fos_oauth_server.client_manager connects to database

[havvg]

When having a service with a dependency to fos_oauth_server.client_manager, the connection to the database is established. I worked around it be marking the fos_oauth_server.client_manager lazy=true.

If that's a valid solution to you, I will send a PR, otherwise please tell me what to do?

This is a serious issue. There is a connection established to the oauth database for every request processed by the Symfony framework as soon as FOSOAuthServerBundle is configured and there is a "fos_oauth: true" somewhere in the app/config/security.yml configuration file. If one has a big website with only a small part of it protected by OAuth, this is a waste of resources.

The problem comes from Entity/ClientManager and Entity/TokenManager which instantiate a repository in their constructor.

lazy=true does not appear as an ideal solution to me, because it relies on ocramius/proxy-manager to be installed.

Here is my attempt to address this issue : #440
