[Tagging] tagging the diameter of a mini-roundabout

[Matija Nalis]

If the actual issue is that HGV cannot pass some road, why not simply mark it as 
`hgv=no`? Besides being simple, it has the additional advantage that routers
will actually already use it and direct HGVs somewhere where they can actually 
pass.

Or if some lenghts of HGVs can pass, but others not, then maxlength=* 
or maxlength:hgv=* or some of the other alternatives from 
https://wiki.openstreetmap.org/wiki/Key:maxlength ?
