DSA/swconfig info in gluon-info

[AiyionPrime]

I'd like gluon to have some sort of tracking how a devices ports are currently managed.
And therefore what capabilities are expected to work.

Any idea what to assess beyond whether swconfig is on the device?

Maybe we can use a common endpoint for this and #2907.

platform.lua already provides a bunch of is_* functions which could be used

I added a is_swconfig() function in my PR

a767421 (#2907)

Edit: Now it's in ethernet module (as switch type detection is a bit more complicated). There is a PR #2915 which the VLAN ui depends on

gluon-info now contains a switch type entry, same for webinterface
