2. `forward` plugin fork
Exposed `parseStanza` to our "alternate" plugin fork.
```
// Exposed to our "alternate" plugin
func ParseForwardStanza(c *caddy.Controller) (*Forward, error) {
return parseStanza(c)
}
```
3. "alternate" plugin fork
Use our "forward" plugin fork instead of the original "forward".
4. "health" plugin fork
Use "/health-check" instead of "/health"
