Add ability to use multiple drivers

[Nelrann]

Hi @stephpy ,

I wonder if it was possible to add ability to use ODM and ORM in the same application.

The goal would be to use ODM for TimelineBundle and ORM for SonataTimelineBundle.

Thank you

Hi,

It'sn't possible at this time. :\

It should be hard to implement but if you want to do it, i accept PRs. :D
