vlan information is already available with `bridge vlan show`. any
specific reason why you want it in
the link dump output ?

Since VLAN info is already in link messages, there is no other option but
dump it in monitor or "bridge link show". Yes, the output may be lengthy
and hard to digest for a human, that is why I put it under "show_details"
kludge - if one is requesting details, he/she should be prepared for
large volumes of data to be shown :)

As Nikolay suggested, it'll make sense to request compressed
output by default, this will be addresses in v2 patch.
