Rename bundle from KNXSwitchAdaptor -> KNXAdaptor

Since this bundle is reponsible for creating the adaptors of all KNX devices supported by fuchsia, makes no sense to call is only switch adaptor
Add KNXAdaptor into the appsgate build
Merge branch 'master' of https://github.com/appsgate2015/appsgate
Add KNX and ARD conf files in the proper directory
