Make headlamp-plugin faster

@skoeva I want to emphasize this part of my comment:

It could be made async, so it doesn't block the user getting work done.

If the check is done async, then it can show the message some moments later. This avoids having state, and has the benefit that it isn't slow once a day. The user is never slowed down in their work.

Are you having this issue in just the npm start command?

That should usually be only run once, and then the command just sits there watching for changes - with no update check done. I understand it would be more of a problem when the npm start was buggy and it had to be run on each change.

It could be made async, so it doesn't block the user getting work done. I think it uses npm internally, which could be switched to a direct https call.

During the "watch" bug it was certainly annoying. But also in live demos it usually just seems like it takes too long.
I think it's worth making faster or only running sporadically, but certainly not urgent.
