rewrite eradius

v3 rewrite of eradius, major changes:
* clients and servers are now started and configured through APIs, not
  app env settings any more
* IPv6 support
* supports multiple server and client instances
* metrics are optional and callback based (allows the easy use of other
  metrics frameworks)
* distributed handlers are no longer support, use erpc to replicate in
  use case specific code if needed.
* removed proxy support (use freeradius or similar instead)
