Fix notice emitted by KnpPaginatorBundle PaginatorConfigurationPass
Add documentation on pagination related components

not depending on a factory service to perform injections.
This may improve performance, removes unnecessary code,
and makes AbstractAuthorizationChecker more flexible by allowing __construct to be overridden.
