Multi-personality polylith binary (#1552)

* Initial work oon multipersonality binary

* Remove old binaries

* Monolith and polylith binaries

* Better logging

* dendrite-poly-multi

* Fix path

* Copyright notices etc

* Tweaks

* Update Docker, INSTALL.md

* Take first argument if flags package doesn't find any args

* Postgres 9.6 or later, fix some more Docker stuff

* Don't create unnecessary e2ekey DB
