Refactor for more flexibility

* Move from gcfg to toml configuration because gcfg was too restrictive
* Implemented gateway which has support multiple in and out bridges.
* Allow for bridging the same bridges, which means eg you can now bridge between multiple mattermosts.
* Support multiple gateways
