Remove "stuff: will_be_there:true"

Describe the bug When entering the UI, a modal flashes past quicky, which is a bit distracting: https://github.com/bloomberg/goldpinger/blob/58285945f68b28da9bd2416e5c5c25a1375c943c/static/index.html#L203

To Reproduce

1. Go to UI

I have the same problem

Fun fact: that modal actually dates back to the first version of goldpinger, which was slower especially on larger clusters :)

I think that we could do without it now. I've marked the issue as good first issue.

Thanks for raising that!
