Add symfony expression in exclusions/expositions

[nicodmf]

I'm not sure this isn't implemented yet, but i see many use case, specially which control the parent group when depth is more than one.

By example :

@ExposeIf(group == 'list' and depth <= 2)

or

@ExposeIf(group in {'list'} and depth <= 2 and 'User' not in parents() )

implemented with #673

Thanks :)
