Firebase uploading v0

[denar90]

Proof of concept for #52

---

I've played with firebase and here what we got:

• uploading trace to firebase and reading it
• no nice gfycat-style-urls (only filenames in storage), just ugly e.g http://localhost:8833/?loadTimelineFromURL=https%3A%2F%2Ffirebasestorage.googleapis.com%2Fv0%2Fb%2Ftimeline-viewer-94e04.appspot.com%2Fo%2Ftraces%252FChimpanzeeHedgehogMoleScorpionvulgar%3Falt%3Dmedia%26token%3Dbf39fc43-2531-431e-9f27-0328e942c859
• no feature for removing traces from storage after 90days, I suppose it has to be handled by firebase Functions. (need more investigation)

If we really need to support of response from server in format like

{
  raw: 'https://chromedevtools.github.io/traces/CuriousRedCrow',
  view: 'https://chromedevtools.github.io/timeline-viewer/?loadTimelineFromURL=https://chromedevtools.github.io/traces/CuriousRedCrow'
}

then I suppose we have to write our own proxy and host it...

P.S. How to setup

1. in storage.js append your own config (one more question how to hide it, has it be hidden)
2. allow CORS to cloud - https://firebase.google.com/docs/storage/web/download-files?authuser=0, section CORS Configuration
