* React UI: Support custom path prefixes

The challenge was that the path prefix can be set dynamically as a flag
on Prometheus, but the React app bundle is statically compiled in to
expect a given path prefix. By adding a placeholder value to the React
app's index.html and replacing it in Prometheus with the right path
prefix during serving, this injects Prometheus's path prefix into the
React app via a global const.

Threading the path prefix into the different React components could have
been done with React's Contexts (https://reactjs.org/docs/context.html),
but I found the consumer side of context values to be a bit cumbersome
(wrapping entire components in context consumers), so I ended up
preferring direct threading of the path prefix values to components that
needed them. Also, using contexts in tests is more verbose than just
passing in path prefix values directly.

* React UI: Improve styling of autocomplete sections

I removed the Card-related components and went back to normal <ul>/<li>,
since the style that Cards added just got in the way (like adding extra
borders and rounding, etc.), and from the examples at
https://getbootstrap.com/docs/4.3/components/card/, it doesn't seem like
multiple Cards are meant to be used as part of a larger list
(style-wise).

This makes React UI URLs look nicer than the previous
/static/graph-new/app.html, but internally still serves all React UI
files from the compiled-in static assets directory.

Also, to allow future usage of the React / Reach router, we need to
serve the main React app's index.html on certain sub-paths that
correspond to current Prometheus's UI pages, instead of trying to serve
actual files that match the provided path name.

* web/ui: handle null case

The call might sometimes return /api/v1/label/__name__/values the
following:

```

```

Then the `index.js` file assumes that `data` is not `null`. However,
that assumption fails and then we get this error in the console:

```
graph.js?v=foo:317 Uncaught TypeError: Cannot read property 'length' of null
    at Object.success (graph.js?v=foo:317)
...
```

Then it becomes impossible to, for example, send a simple query like
`time()` and graph the results.

Fix it by using an empty array as the result if it is `null`.

If the difference between the current time on a client and time on a server is quite big, Prometheus tries to show a related warning in UI on the Graph tab. But in the code, an incorrect context is used to invoke this method. As a result, an error is showed in the web developer console and the whole page stop working at all. This commit fixes the context.
