Display configured filter
LTTng Tools 2.1.0 offers the ability to configure filter when enabling events. It currently displays only that a filter is configured for command "lttng list <session>". It would be beneficial also to display the actual filter expression in the command output instead of displaying only [with filter].

I'm moving this feature for 2.6 unfortunately.
We are quite close to the rc1 of 2.5 and I feel uncomfortable adding this right now since it requires a lot of code and adding stuff to the public ABI/API. I usually prefer changes on the API done way before so people can play with it and we can make adjustment instead of rushing it.
I've started a branch containing some code for the feature but it's not working at all for now.
