app service unix socket support (#3022)

Browse source 
This is the last part of unix socket support to talk to app servers, go
based app services already support unix sockets:

5a68173fe3
```
appservice:
  # The address that the homeserver can use to connect to this appservice.
  address: unix:///var/snap/matrix/current/whatsapp.socket

  # The hostname and port where this appservice should listen.
  hostname: /var/snap/matrix/current/whatsapp.socket
  port: 0
```
