v0.5.0

This release marks the first release where NeonVM has been merged into
the same repository. It was last at v0.4.6, so we've bumped to v0.5.0 as
a kind of clean slate.

Features:

- Added "dump state" endpoints to autoscaler-agent and scheduler plugin.
  Refer to https://github.com/neondatabase/autoscaling/pull/76 for more
  information. (The endpoints are enabled by default).

No protocol changes.

There have been significant changes to testing - everything is run by
the Makefile now. Refer to https://github.com/neondatabase/autoscaling/pull/91
for more information.
