[Dashboard] Add the new dashboard code and prompt users to try it

[mxz96102]

Why are these changes needed?

Immigration of the ant new dashboard, like we talking about last week.
The old dashboard is also maintained inside, we will remove it once everything is ready.

The old dashboard connects with the new one with a link.
Instead of using change origin, using package.json proxy to connect API server to backend

I don't understand the title of this PR. @mxz96102 Are you trying to enable the new dashboard by default?

@kfstorm Users are using the current dashboard by default, and we provide a button to guide them try new dashboard.

@mxz96102 How about changing the title to "[Dashboard] Add the new dashboard code and prompt users to try it"?

@raulchen @mxz96102 I just tried this out, but it seems that the jobs, actors, and logs pages are not working.

• The jobs page just hangs forever with a loading icon.
• The actors page renders but I started an actor on the cluster and it did not show up in the dashboard.
• The logs page only shows "Failed to load" (screenshot below).

This may due to code sync, I didn't update the backend code with this branch. Now I merged the master, these problems are supposed to be solved now.

Thanks @mxz96102 I'll take another look tomorrow.

@mxz96102 @raulchen it seems to be working now!

I'm ok to merge this with the following change: can we place change the naming of the buttoms from "TRY NEW DASHBOARD" to "TRY EXPERIMENTAL DASHBOARD" and "BACK TO LEGACY" to "BACK TO EXISTING DASHBOARD"? I'd also like it if we could remove the "SUMMARY" page entirely as it's basically just a blank screen right now.

I have a bunch of other small feedback on how we can improve this dashboard before we ask for feedback from OSS users. I will file this under a github milestone in the couple of days.

@edoakes Thanks, I'm glad to have feedback with your team, it's important that we can hear your opinion and improve dashboard together
