return an error for multiple use of some plugins (#1559)
* plugins: Return error for multiple use of some
Return plugin.ErrOnce when a plugin that doesn't support it, is called
mutliple times.
This now adds it for: cache, dnssec, errors, forward, hosts, nsid.
And changes it slightly in kubernetes, pprof, reload, root.
* more tests
