Remove parts of a previous connection monitor.
To add some context (as far as my memory goes) to the multiple connection
monitor features the product has, `stats` (currently named `connection status`)
was introduced at the Flash client back in ~2016. @fcecagno and I did it
as a BigBlueButton's Summit activity. Our work was squashed into a single
commit in 92554f8b3e :).
I'm not sure about the whole story behind `network information` (the late
connection monitor added to the HTML5 client) but I assume it should work
as a collector for a bunch of different connectivity monitors. I remember
when it was introduced but I don't know why it wasn't adopted. My best guess
would be because of some performance issues the `user list` had back then.
To follow on why `connection status` replaced `network information` at the
HTML5 client, when I did the `multiple webcams` feature I had to refactor
a big chunk of the `video provider` (#8374). Something that wasn't really
helping there was the adaptation of `stats` that was made to show local
feedback for each webcam connection. Although this feature wasn't being
used anymore, `network information` did rely on that to build up data. With
this monitor gone I assumed it was my responsibility to provide an alternative
so I promoted Mconf's port of the Flash `stats` monitor to BigBlueButton's
HTML5 client (#8579).
Well, that's my perspective on how things went for those features. If
anyone would like to correct me on something or add something else on
that history I would appreciate to know.
Refactor the external videos collection, moving the logic and functionalities
outside of /imports/api/meetings to a new location in /external-videos/server/modifiers
in order to decrease the coupling between the functionalities, favoring
the maintenance.
