Changes in synapse v0.27.0-rc1 (2018-03-14)

The common case for running Synapse is not to run separate workers, but for those that do, be aware that synctl no longer starts the main synapse when using -a option with workers. A new worker file should be added with worker_app: synapse.app.homeserver.

This release also begins the process of renaming a number of the metrics
reported to prometheus. See docs/metrics-howto.rst <docs/metrics-howto.rst#block-and-response-metrics-renamed-for-0-27-0>_.
Note that the v0.28.0 release will remove the deprecated metric names.
