matrix well-known server

This is a small service that runs alongside a Matrix Synapse in order to direct traffic to it via .well-known/matrix/*.

We currently satisfy two URLs formats:

• .well-known/matrix/client: as per the client-server spec, ie. m.homeserver set.
• .well-known/matrix/server: as per the federation spec, ie. m.server set

Usage

This is automatically ran as part of the kubernetes machinery for Synapse. See //app/matrix/lib/matrix.libsonnet for more information.
