Add missing keyframe parameter to videoroom configure

[Qizot]

It happens that the configure function for videoroom plugin was missing the keyframe parameter that is supposed to request a keyframe for given publisher handle.

Just like with the last PR, can we bump the version and publish the package? Thanks!

Hi @Qizot thanks for the patch.
I'm afraid I can not tag a new version for every commit on the repo, it'd quickly become a mess!
May I ask why you need a release? What about pointing your package.json to the git repo on a specific commit?

@atoppi I guess we can point to the git repo, don't worry then.
