[Extensions] extensions priority

[dkarlovi]

I'm doing #69 in my app (will send a PR later) and ran into a problem.

My extension catches the Symfony user token and stores it properly in the processor's token storage. But, to be able to use it, I must merge the user with the Doctrine entity manager (user must be managed to be able to use in Blameable or similar), all this works.

Problem was: after I merged the user, DoctrineClearIdentityMapExtension came in and cleared the map so my onPreReceived() ended up being useless. I've worked this by disabling it and doing the same thing from my onPostReceived, but the problem still remains: extensions should be able to specify their priority.

Also, shouldn't DoctrineClearIdentityMapExtension clear the map from onPostReceived, not onPreReceived?

The priority already supported. Add priority attribute to symfony's tag with a number

I'd prefer to be sure the state is clean before I start processing the message

That's great, I've missed the priority part in the docs, thank you!
