20a136a73c Revisit random-delay 
If enabled it will still delay randomly between 0-5 seconds.

However, the functionality to fine grain this is added.
Both seconds and milliseconds are supported now. Moreover,
min/max values for random delay can be condigured through
pflag params

3197ad3e45 Register hostname and version in cache 
If the caching server is online, podinfo registers its hostname and version in Redis. The set expires after one minute and it's refreshed every 30 seconds.

0ff49e5057 feat: Add H2C support 
`podinfo --h2c` allows upgrading a HTTP/1.1 connection to HTTP/2 Cleartext.

This allows `podinfo` to be used in e.g. a H2C load-test like `echo "GET http://localhost:9898/status/200" | vegeta -h2c`, or a H2C connectivity test like done with `curl -v http2 http://localhost:9898/status/200`.

I have manually verified this to work by running `curl -v --http2` on macOS and seeing the H2C upgrade happens onl when `-h2c` is provided to `podinfo`.

Without `-h2c`:

```
$ curl -v --http2 localhost:9898/status/200
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 9898 (#0)
> GET /status/200 HTTP/1.1
> Host: localhost:9898
> User-Agent: curl/7.54.0
> Accept: */*
> Connection: Upgrade, HTTP2-Settings
> Upgrade: h2c
> HTTP2-Settings: AAMAAABkAARAAAAAAAIAAAAA

{
  "status": 200
* Connection #0 to host localhost left intact
}
```

With `-h2c`:

```
$ curl -v --http2 localhost:9898/status/200
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 9898 (#0)

198211e20b Add delayed chunk endpoint 
Adds an endpoint that does chunk based encoding. The endpoint just stalls
and eventually returns the stall time.

Similar to the delay endpoint but in a chunked maner.

Fixed up the metrics interceptor to wrap ResponseWriter correctly too.
